NEWS / UPDATES
I often update this website as my knowledge of tektites increases and new ideas develop through reading and discussion with other tektite enthusiasts. I have always set out to keep modifying and correcting this website. Some ideas that I have been fairly certain about in the past have proven to be wrong, but gradually I feel that ideas are becoming more solid.
05 August 2016 - I'm still here, but this site is rather clumsy to update so I probably going to start a new site at some point. In the meantime there are a few good groups on Facebook (2 of which I run) where you can catch up on tektites and ask questions - just do a FB search. I have just done an update on stolen tektites. I had a large number stolen by an ex-friend. I am still looking for a few. See the link to the left.
15 February 2014 - You can see my latest abstracts for the LPSC, one co-authored with Andreas Krauss, at Deformation and Spallation Mechanisms in Tektites and Agglutinated Australasian Tektites. This month I went to Anda, Pangasinan in the Philippines to investigate the amazing Anda-type sculpture. I came back with some fine specimens and soil samples. I've done a write up, but need to sort out the pictures. More coming soon on this front. These days I often post on the Facebook Tektite Group and you can see the unedited Anda photographs there (but no write-up)!
30 January 2014 - I have updated the Smithsonian page - thanks to Sheryl Sims for the images!
11 December 2013 - I was very fortunate in being able to attend the official opening of the Muzeum Vltavínů or Moldavite Museum in Southern Bohemia, Czech Republic. Check out this page to see a slide show of the visit to the Museum, the town of Český Krumlov and jewellers and a field trip to the Chlum sand pit. I have spent the latter half of this year working on Henry Beyer tektite material that has found its way into my collection and on Beyer literature which is mainly in the University of the Philippines, Diliman Library, with a small part in my possesion. You know the rare book 'Philippine tektites' Parts I and II? Well at least part (if not all) of unpublished Parts III and IV exist! We have embarked on digitising these data to see what we have - it's a huge job with 122 boxes of tektite, ethnographic and archaeological writings. We will establish what is there and digitise all the tektite material.
28 June 2013 - Here is my latest kmz file of tektites. Once you've downloaded the kmz file open Google Earth, File (top left), Open. I've also placed a link on the Distribution page. Now I remember though I did update this file again slightly (mainly Central American thanks to Brian Burrer), so this is just marginally out of date. I'll do a whole new page when I have the time. I first shared this on the Facebook tektite page about a month ago btw.
23 February 2013 - I have recently produced an abstract for the 44th Lunar and Planetary Science Conference entitled 'Review of the Australasian Tektite Source Crater Location and Candidate Structure in the Song Hong-Yinggehai Basin, Gulf of Tonkin'. Check out my new page called 'Possible Crater?' I have been very busy lately trying to finish off my book. It's practically there (as it has been for 6 months), but I'm just making corrections and improvements. It's a slow process, especially as I have little free time between work (as a consultant wellsite geologist) and a 2 year old boy! I have also been working on the Henry Otley Beyer Collection. I have 472 boxes of material, variously labelled, mainly Philippine tektites (small) and obsidian. I need to research the labels some more and then I will share. It really brings his book to life though! I'm pleased this collection has been rescued as it is important to tektite study and Philippine natural history.
25 September 2012 - Just got back from US - California, Nevada, Arizona. Visited Meteor Crater in Arizona and the Griffith Observatory in Los Angeles, California. Some nice pictures here! The book is almost complete - around 420 pages. Hope to publish by end November, but this may be delayed to March 2013 depending on other commitments. Very keen to get this book out though as it has some interesting new information. Also pleasure to meet Johnno Cabassi in Las Vegas and examine his 1200g tektite - probably raised more questions than it answered! See Largest Tektites.
06 July 2012 - Wow - it's been almost a year since I updated this site. Time has flown by - too busy working. My main focus lately has been to finish my book on Australasian tektites. It's 400 pages long with some ground breaking material, which supersedes some of the information on this webpage. It's real close to being finished so I hope I can push it out by the end of the year, but I'm really busy in (paid) work. I have also been sidetracked in working on the tektite distribution pattern. Here is a taster of what I've been doing on the Distribution page. Come back in 9 months or so and you'll probably see a whole lot more - there are some extremely interesting findings and maps on my desktop, which I hope will lead us a step closer to the source crater being found! I'm going to focus on the new book, then once that's done I'll be moving over to www.tektites.info with a significantly updated site, but that's still some way off. Also I've acquired a new Victorian Australite collection and a very important Philippine collection. More details to come in the future.
19 September 2011 - Been x-raying again. Updates on the Largest Tektite page and X-Ray Analysis page. The 995.10g specimen contained a 15 mm bubble and the 1,281.89g specimen contained a 60 mm bubble!
10 September 2011 - I'm so proud of my son - he is 13 months old and he can say 'Tektite' so I named the biggest tektite in the world after him! The 1,281.89g tektite now has photographs on the Largest Tektites page.
06 September 2011 - I just updated the Largest Tektites page. I have been working away from home for the last 6 weeks and in this time I have acquired a 995 gram and new record breaking 1,281 gram tektite from Paracale, Bicol, Philippines. This year, 2011, has been a bumper year for large tektites - no idea why (maybe because the price increased, but these are new finds so I suspect not). More photos to come when I get home!
21 July 2011 - Today I have been looking at the ballistic trajectories of tektites. Not an area of expertise, but certainly one of interest. Here's what I got up to today.
15 July 2011 - I have added all the remaiing photos (non-tektitic) to the Beyer Catalogue page.
12 July 2011 - I have spent ages going through the x-ray images and trying to edit them so you can see the bubbles. I include a powerpoint presentation. Some interesting results with regards bubbles in larger philippinites. View them here: X-Ray Analysis.
08 July 2011 - Check out the original tektite photos of Henry Otley Beyer on my new page Beyer Catalogue. These stunning images were found in an attic in Quezon City, Metro Manila, and I was lucky enough to get hold of them! They include plate/type specimen photos and photos of the Novaliches dam construction archaeological dig in 1926, same place, same month, in which Philippine tektites were first discovered. These are so rare that they shouldn't exist!
07 July 2011 - Today I did some more x-raying (so more to come) but the update for today is on the largest philippinite ever recorded at 1,194.8g. See Largest Tektite for details including an x-ray image of the 70 x 73 mm diameter bubble it contains!
06 July 2011 - I've been x-raying tektites! Take a look at X-Ray Tektites.
14 June 2011 - A brief update on the Largest Tektites. I have been fortunate enough to acquire the largest Philippinite recorded, at approximately 1,195g. This is the same specimen originally reported to be 1,250g. It will be accurately weighed shortly when I am back in Manila.
24 April 2011 - The European Tektite Forum 2011 was a great event. I have so much information and many photos to share with you, but sadly no time! I'll document the trip within the next 2-3 months, so keep an eye out here! In the meantime please view the raw and unedited Photos, which currently lack annotations/descriptions/information.
21 March 2011 - You thought meteorite laws were tricky and often open to interpretation! Presenting my new page on Tektite Ownership and Export Laws. At least we can be thankful that tektites are geographically resticted!
11 March 2011 - Thanks for the photos of your collections! I have added a few pages - you can't get enough photos of tektites! Thanks to Daniel Sutherland (a great representative collection), Rick Self (fantastic Bediasites) and Brain Schroeder (amazing faceted tektites/impactites). I have also added a little to the Fakes and Frauds page. I am always annoyed at the number of fakes on ebay - some are there through ignorance, others set out to defraud you. Moldavites are the main fakes - help yourself by being familiar with what Moldavite look like, ask questions and buy from reputable/recommended dealers.
26 February 2011 - A couple of plugs! Firstly there is an informal tektite meeting in Brno, Czech Republic on 15-17 April 2011. It is being organised by Milan Trnka. I'll be there and I believe a few other European collectors will attend. Secondly if you want to buy a telescope or meteorites in the Philippines then I highly recommend my friend Allen Yu. See his new website here. That was a shameless plug!
25 February 2011 - Presenting the Des Leong Collection of Tektites. This is now catalogued and incorporated into the Aubrey Whymark Collection of Tektites. Also added a few photos on the Australasian Tektite page; Sculpture/Morphology page; Philippinite page; Australite page. Really need to update some of these pages, but no time. If you want my latest views then see my Presentation.
20 February 2011 - On 19 February 2011 I did a lecture for the Philippine Astronomical Society at Rizal Technological University in Manila. View the powerpoint presentation and photographs at Presentations. I have also added a Download page, where you can download tektite articles/data/presentations that I've produced. I'll be adding to this in the future as I have stacks of info on my hard drive.
07 February 2011 - An alleged 1,250g Philippinite comes to light (probably actually weighs less). Keen to know where this ended up. Read my gripe and see photos on the Largest Tektite page - I'll get over it eventually! Congratulations to the buyer - please do let us know the details.
05 February 2011 - FYI I have purchased Des Leong's entire tektite collection. This includes some super rare specimens. I'll do a page soon! It's a shame that Des is stopping dealing. There isn't any other person that I would trust on ebay or with a Philippine tektite site (in the Philippines). Personally I'd only deal with these guys by seeing the tektite and paying cash, but you take your chances!
31 January 2011 - If you want to see a huge Australite then scroll to the bottom of Private Collection #1! I recently acquired some great missile test photos for your comparison with Australites. take a look at my new Missiles page!
24 December 2010 - Des Leong has recovered a 1,018g Philippinite. The second largest known specimen from the Philippines. See the Largest Tektites page for details!
08 December 2010 - Today I made a new page on publication history of tektites. It's interesting to see how the numbers of publications has varied over time and what has impacted on the interest of tektites.
07 December 2010 - Wow, I've been busy this year and the tektites have suffered! Busy working, busy with a new baby bot called 'Atom'. The tektite collections has, however, continued to grow! Today I updated the bibliography. There are loads of new references, many of which are derived from Milan Trnka's reference list. This took literally days and days (probably weeks actually on/off) to update and cross reference, but it's a great resource so I hope you enjoy it.
06 March 2010 - The Planetarium in Manila has now re-opened! It includes some Henry Otley Beyer specimens. See the tektite and meteorite displays here.
01 January 2010 - To celebrate the New Year I have posted some new photos of Anda tektites I acquired in the last year. See the Anda Gallery 2. Happy New Year!
26 October 2009 - Today I got the most amusing fraudulent email ever. Check out the bottom of my Fakes and Frauds page. I have an article coming out in the November 2009 Meteorite Magazine and I am currently writing an article for the Geological Society of the Philippines. Keeping me busy. Eventually I'll update this website with the latest data.
06 October 2009 - I've launched a new website to raise some funds. Please check out www.tektiteshop.co.uk. Thanks! PLEASE NOTE (09 Nov 09) that I've now taken this site down to concentrate on my research - it may appear again in the future though!
08 September 2009 - Check out my new Stretch tektites page. Exciting news - I have two Philippinite stretch tektites. Not the classic shapes as in Indochina. These Philippinite stretch forms must have formed on the way out of the atmosphere, because when they re-entered they were solid! Clear rotation and stretching evident though! Also updated a few minor details such as the age of Australasian tektites (currently estimated to be 803,000 yrs old (+/- 3,000 yrs)). Meaning to do that for a while. Currently writing, photographing and cataloging my tektites. Cataloged 200+ kilos of Philippinites so far. At least 100 kilos to go I think, maybe 150 kilos.
22 August 2009 - Another brief update on Beyer's Monster. The largest complete Philippinite splashform is in the Corning Museum of Glass. See the Largest Tektites page.
20 August 2009 - A brief update on Beyer's Monster on the Largest Tektites page. I'm still working on tektite classification and also on some old Beyer papers. I have too many tektites to catalogue and too many new papers to read (a few hundred). My wife is off to the US in September and I'm staying in Manila to work on tektites. I figured there was little to see as she wasn't going to Texas or Georgia....
15 August 2009 - I have just featured a new private collection from Werner and Sandra Schroer. Many thanks for sending me photos of your collection! I have also updated details of the largest Philippinite on the Largest Tektites page. The big question is: 'Where is this tektite now?'
30 July 2009 - I have updated my extensive bibliography. In doing so I have unfortunately lost the formatting (bold type and italics). You'll find 793 articles downloadable for free (some may now charge a fee but were free when I accessed them). To date I have listed 2,581 articles and there are certainly more out there! On another subject I am currently cataloging and measuring/weighing hundreds of kilos of tektites. It's a big job. I have also drawn up a classification scheme for Indochinite and Philippinite tektites, but still have a little more work to do before I reveal the draft version.
18 June 2009 - I am in the UK and have just shipped 5 crates of tektites and tektite references to the Philippines! Now I will have all my tektite data in one place!
19 May 2009 - Sorry no additions for a while! I was working on an article for Meteorite Magazine. Hopefully this article will be published soon. Also I was making a new website www.filtours.com - it's just supposed to be a simple tour guide to the Philippines. If you've not visited the Philippines then you should - it's fantastic (and so are the tektites)! I am currently working on cataloging, measuring and weighing my Philippinite collection. I've done 77 kilos and still have tektites stuffed literally everywhere! Maybe I have about 300 kilos - I'll find out in time. Some of the fragments are very interesting and may come from huge spheres, theoretically weighing a couple of kilos. Of course this assumes a spherical body, which may not be the case for these fragments. Anyway, work in progress. Just acquired a 658g Philippinite with a big bubble - the tektite should weigh 877g based on it's volume! See it on the Largest Tektites Page.
11 March 2009 - Check out my new Largest Tektites Page. Inspired by the 867g Philippinite that passed through my hands today (I'm holding out for a 900g plus one, but this was a fine specimen!!). More photos to be added tomorrow and hopefully more details to come as I get feedback!
10 March 2009 - Been delayed for work, got up late then made 8 tektite videos. This is my first attempt at 'You Tube', so if you want a boring lecture on tektites then you've come to the right place! More to come in the future!
09 March 2009 - Added a little on ring vortices and Indochinite donut formation. Really interesting stuff. I want to study concavo-convex specimens a little more to understand them better.
06 March 2009 - Just added a section on mining asteroids. Just something I've been thinking about lately together with the application of tektites.
03 March 2009 - I've just got back from my honeymoon in Vietnam. I bought a whopper of a splashform tektite and I'm interested to find out what other large tektites are out there! See my new page Tektites of Vietnam. Also see a map I added, gold distribution in the Philippines, on my page Paracale Mines. Tektites are often recovered from alluvial gold deposits.
16 January 2009 - Happy New Year! Bought another 8 kilos of Bikol tektites. I have too many, but I have big study plans (and no time). I just wanted to quickly draw your attention to an email I received from Radek Ther. 'We would like to inform you regarding activity of the South Bohemian Museum (Czech Republic) and South Bohemian Region. They intend to organise an International Scientific Conference on Moldavites, Tektites and Impact Glasses in September 2009 in Ceske Budejovice. You will find two sheet booklet enclosed to this e-mail about this conference. We kindly ask you if you consider to participate in this conference to fill up the preliminary registration form and send it back to e-mail: email@example.com no later than January 31st, 2009. You can also find complete information and files (booklet, preliminary registration form) to download on website http://www.therra.cz/moldavites.html in english'.
16 December 2008 - I have a new page with some images of the gold mining operations at Paracale, Bikol Region, in the Philippines. You'll be surprised at the conditions the miners endure in order to recover gold (and tektites).
10 December 2008 - Finally I have updated the Indochinite formation and Philippinite formation pages, which was long overdue. These now reflect my current thinking. Indochinites were often molten when they hit the Earth's atmosphere, resulting in some great morphlogies! Philippinite morphology seems to depend on both size and whether the tektite was oriented during re-entry. A perfect sphere may be very unstable and spin, thus distributing re-entry heat more evenly. Oriented flight makes 'biscuits' and 'hamburgers'. Unoriented flight makes perfect spheres, breadcrusts and small grooved spheres. At least that's my current thinking, plenty of work still to do.
04 December 2008 - Today I have quickly added the lithology data, under the heading 'Soil Samples', that I had on Belitung, Indonesia and Paracale, Bikol, Philippines. Both these places produce heavily etched, U-grooved tektites. It's interesting to see the similarity in lithology between these two regions. I bought a few more tektites from Bikol - some from the mountains and some from 5-6ft deep water in the sea. No differences in sculpture between the two.
02 December 2008 - Thanks to Arum Suryanti, who I worked with in Maersk Oil Qatar, the Indonesian translation has been improved on my Billitonite Formation page. I have now analysed soil samples from Belitung and Bikol and hope to publish a page soon. I have more Philippinites now from Paracale and also some more from Infanta in the Quezon Province. I now officially have no more space for tektites in my apartment - there is so little space that I even have 10 kilos in the fridge!
05 November 2008 - Well I've been to Belitung! What a wonderful place! I've learnt a lot and I share all my information here! I particularly enjoyed actually seeing the place where the tektites are found - I want to go back there and hunt for myself! OK - My trip details here, about the tin mines here, about Billitonite formation here and finally my billitonite collection gallery here. One more page too - Fake Tektites!
28 October 2008 - I've been buying more tektites (17kg today, mainly from Bikol) and also researching. I added a few locality pages today - Guimaras, Masbate and Belitung (formerly Billiton). I am excited to be going to Belitung very shortly. I am keen to find the truth on these tektites, particularly with regards cost! More to come here!
10 October 2008 - Wow it's been ages since I updated this site! I have been very busy with my work and also with my tektite reference list - not updated, but you can email me if you want a copy. I have acquired some more references (thanks if you sent me some) and I think I have around 1,680 ish now. Also I have bought maybe another 33 kilos or so of Philippine tektites. I must have lots now! I have started to make measurements to understand the original size of the tektite sphere before re-entry and how this relates to the final morphology. I have acquired a beautiful and very very rare teardrop breadcrust with one old break - I've never seen one like this before. An amazing specimen that totally clears up any doubt about the orientation of 'hamburger' types, which appear to relate to spheres larger than those that produced the true 'breadcrusts'. I'll have to do something on this soon. I hope that within a few months I'll have a really solid understanding of Philippine tektites. Ultimately I need to do some glass sphere experimentation though.
Above: A rare teardrop 'breadcrust' and a 'hamburger' from Paracale, Bicol. Top is posterior, bottom is anterior.
09 July 2008 - My job was delayed giving me the chance to acquire tektites from a new locality via one of Des Leong's suppliers. Take a look at my new Sipalay, Philippines locality page. Now compare these tektites with other localities.
04 July 2008 - Happy Independence Day to Americans! I have been extremely busy lately with work and getting married. Still, I have managed to find a little time for the tektites. There is an update on the Quezon City tektites, Philippines. I have added new photos in the collectors page for Peter Simmonds and for myself, Aubrey Whymark (2), showing my new Australite collection. I made a minor correction to the Philippinites page (thanks Jason), but I should review it more thoroughly at a later date. Also see Des Leong's site (and follow the links) for images of the Western Australian Museum in Perth - on the same page you'll also find links to images showing the field collection of the australites in my new collection. I'll also probably post these images on this site at a later date. Ah, one more thing - I also have a new 11.5g Georgiaite, see my Bediasites/Georgiaites page. It was collected by George Bruce in the 1950/60's and is remarkably unimpressive (but slightly more impressive than my other Georgiaite)! Finally, I am doing some major work on my tektite reference list (but struggling with lack of time), so no updates I'm afraid. There have been some minor corrections and I have found some more papers freely available online. Watch this space in a few months.
30 May 2008 - Well I am back to work again for a month or so. I have mainly been working on tektite references. I have an improved list now, that I can email if you want; I'll be updating the list again in a month or so anyway. I now have around 1,550 of the references. Today I bought around 150 kilos of Philippinites. Suffice to say, my future wife is not very happy. At all. Anyway, amongst these tektites were some specimens from Quezon City - unremarkable, but interesting as they come from a very well documented site. If anyone wants to trade tektites from different regions for Philippinites, then I am open to offers and can do a good deal. I'm real busy the next month though, so bear with me!
20 May 2008 - I've been busy today, maybe it's the Japanese chocolate coated coffee beans I've been eating (like special M & M's)! Des Leong kindly sent me some images from the Western Australian Museum. I'm drooling at the sight of these tektites. Olaf Gabel has kindly added to this site with some images of his collection. You can see more on his webpage. I have updated my Indochinite page, which I haven't been happy with for a while. Hopefully more to come on this page. Finally I have added some images of the Australite collection I bought a while back in the Phillipines, via Australia. I have a few more Australites in UK and a couple of kilos arriving from WA very soon - watch out for more posts!
15 April 2008 - A new collection of tektites is shown - Collection #1. Apologies if pages are not displayed. I am still having issues with the website publisher and I'm not sure how to resolve the apparent conflict between the old and new page names. The pages are out there somwhere though!
10 April 2008 - I've changed the ends of the page addresses from numbers to words. The homepage is the same, but if you have links to any other pages then you may need to update these. Apologies for the inconvenience, but I hope this will make the page run smoother. Let me know if you have problems! Also check out Rob Grant's tektite collection - added today!
9 April 2008 - New pages! Tektite People and Private Collections. First featured tektite person is Henry Otley Beyer - father of Philippine tektites. More famous tektite people to come! I've also started a new series of pages featuring tektite collectors. I know some of you guys have some amazing specimens, so why not email me a few pictures and let me share them with fellow collectors?
8 April 2008 - I've updated the reference list once again. Loads of good reading on tektites for free! I'm still collecting references and have about 1,450 now. I'm going to keep going until I have, or have access to, all of the references! I have bought some originals including signed papers/books by Henry Otley Beyer and Charles Fenner and also originals of the classics like Suess, F. E. 1900 where the term tektite was first coined. Also a couple of volumes containing papers by Lacroix who first described tektites from Indochina and from the Ivory Coast.
25 March 2008 - What's new? Not a lot - I've been working a lot lately and in my few days off my computer has been playing up (the joy of Windows Vista I suspect)! I have an updated bibliography with more free links to papers and minor corrections, which I hope to publish on this website as soon as the computer allows! If you're really keen for a copy I could email it. I have also been collecting other references which were far from free and due to copyright law cannot be distributed. I have 1,131 at the last count!
The latest issue of Geology (Vol. 36, No. 4) looks very interesting with reports of the Australasian strewn field being extended to Antarctica with the discovery of microtektites in Victoria Land Transantarctic Mountains. Another paper in this issue describes a Precambrian proximal impact ejecta from Scotland. Good stuff! Also I have discovered that copies of Silica '96 on Libyan Desert Glass are still for sale. Get them now is my advice!
I see that a new dealer has emerged at Indonesian-tektites.com - Billitonites have been selling for very high prices and as with everything it is all about supply and demand. In the case of Billitonites the supply appears very low. I hope in the future this will change, as I can't see any reason why Billitonites should be significantly rarer than Philippinites - many Philippinites are for sale at Des Leong's site www.tektiteinc.com. Perhaps the miners simply don't yet realise the value of the many tektites they must find. Anyway I welcome the opportunity to buy tektites from Indonesia, but I'll be spending the money on an airfare to buy direct at hopefully a fraction of the cost. Billitonites formed in a very similar way to Philippinites, with the U-grooves on the anterior being due to chemical etching of thermal stress cracks.
Finally, on the subject of supply and demand - when are we going to see an Ivory Coast tektite dealer - again, get the right place and I bet these tektites are common. Also I saw a documentary on diamond mining in alluvial deposits in Liberia - I bet 'Ivory Coast' tektites are waiting to be found in Liberia. These manual 'sifting' operations are ideal for finding tektites.
28 February 2008 - I have added a brief bit on the Grooves and Navels page and on the related Navel Protrusions page with regards a possible navel formation mechanism - Hertzian cones. Also on the 26 Feb I placed a few water worn Philippinites into a strong sodium hydroxide solution. Here they will stay for 3-6 months or whenever I next return to the United Kingdom. Will they be etched?
24 February 2008 - I have changed the Home Page slightly and added a little to the Tektite Stone Tools page. No big changes! Did you know that von Koenigswald, a palaeontologist famous for his involvement in the Java Man, also wrote many papers on tektites? Tektites were found in the same deposits as Java Man.
23 February 2008 - I have updated the bibliography. Only small corrections and a few new links. It still amazes me how much has been written on tektites!
20 February 2008 - I have added the latest info on the new Davao site, we are still working on it though! Also I have plans in the future of adding a 'Tektite People' page. I'll start with Beyer and then write about other top researchers and collectors. This was inspired by some recently acquired Beyer papers, some of which offer an insight into his life. I have also started a list of all known tektite localities. A massive task considering I am still sourcing references and have a wedding to plan! I'll start publishing versions of the list maybe in a month or two, but it'll likely take a year to finish.
16 February 2008 - Firstly good news! My girlfriend Tere has accepted my marriage proposal on Valentines Day. You can see her (and the ring) by clicking here (opens new window). Before proposing she agreed that am still allowed to spend excessive time and money on tektites, well maybe not precisely them words, but something similar - but the important thing was that she comes before tektites! OK....tektites. I added some more info and photos to the Tektite Labels page. Also I have made a new page called Navel Protrusions. This page includes some amazing photos of Des Leong's new tektite nicknamed 'Shrek'.
12 February 2008 - I have added a few photos to the British Museum page (tektites in the Red Zone) and also repeats of the Libyan Desert Glass photos on the Libyan Desert Glass page. I also added a few photos to the Man-Made Glass page.
11 February 2008 - I have made a new page called Tektite Labels, following the discovery of some labelled specimens in Des Leong's collection. Four of the specimens have a fascinating and tragic story -well worth a read. Had these specimens not been labelled we would not have known the true significance of them.
04 February 2008 - INTERESTING NEWS (news to me at least) - I emailed the Earth and Planetary Sciences Department in the Western Australian Museum. I was enquiring how to go about exporting a collection of australites that I recently acquired. This is the reply:
'Because they are not meteorites, tektites are not covererd by meteorite legislation in WA. They were also removed from the control lists of the Federal Protection of Movable Cultural Heritage Act (1986) some years ago. In effect there is no impediment to the export of tektites from Australia'.
This is good news for tektite collectors, but I think we should all be encouraged to work closely with museums and academic institutions, particularly with regards unusual specimens. This way everyone is happy and the current legislation works perfectly.
04 February 2008 - I've added a few photos to the British Museum of Natural History tektite page, but still a few more to come. Also some of the same photos to the Ivory Coast tektite page. Also a breadcrust bomb photo to the Volcanic Bombs page. In the early days I wondered whether breadcrust bombs and breadcrust tektites perhaps had a similar formation mechanism: they don't!
03 February 2008 - A few more museum pages have been added. Included are a few links, but I'm really just waiting for photos of the tektite collections. Any images will be gratefully received (firstname.lastname@example.org)! Also I added a couple of images to my grooves and navels page - they show interesting 'crescent' fractures around the navels.
30 January 2008 - I've added a couple of Libyan Desert Glass photos, added some photos to the Very Quick Guide to help people differentiate the anterior and posterior of their tektite and finally added a few more photos to the Australite page.
30 January 2008 (very early hours) - I've just added a load of new pages relating to tektites in Museums. I'm keen to discover the great (and not so great) tektite collections of the world. Perhaps I could do the same with private collections some time in the future.
Also, I have to tell everyone about my dream! I had a dream, but not like Martin Luther King. Instead I was geosteering a horizontal oil well and then we hit a layer of tektites - all button australites (which for some reason were surprisingly deeply buried and in surprisingly old strata, but nevermind). Anyway the flanged buttons came out the hole in perfect condition (another rather remarkable fact) and I was going mad trying to collect them all! This is my mindset folks - welcome to my world!
29 January 2008 - I have further updated the reference list, now called the bibliography and divided into 4 parts. I found a few more papers in Czech and also worked on Henry Otley Beyer's papers. He did a lot of work on tektites from the Philippines between 1928 and 1962. Many articles seem to be unpublished and are only available on microfilm now, which in some cases has become unreadable. Beyer's material was sold to Australia ?Melbourne or Adelaide I think, so perhaps the originals are there. This historic data is interesting - it took Beyer 3 attempts to write his 1928 paper announcing the discovery of Philippine tektites, which he named Rizalites. Also I have removed the 'Tektites are Exciting' page. I liked it, but it's not the direction I want this site to go in - just a bit of fun! Finally, on the Very Quick Guide page I added a few comments on tektite orientation - I really need a few diagrams though.
Libyan Desert Glass, more of an impactite than a tektite, but I was amazed at how green it can be - well yellow-green. Expect a page soon.
Also visited the Natural History museum in London, UK. The tektite display includes some nice Ivory Coast tektites, but is much reduced. A dozen or so average moldavites, half a dozen average Indochinites and a piece of Libyan Desert Glass. No Philippinites, Malaysianites, Javanites, Australites or North American tektites are displayed. Disappointing..... I'm going to start some museum pages, so tektite people know where to visit and where not to.
26 December 2007 - Today I made a quick update of my Philippinite Formation diagram. I'm sure further editions will follow, but it's getting there!
21 December 2007 - Updated the Paracale, Bikol Region page and also the Anda, Pangasinan Region page. Some nice tektite photos. I want to add more pages, particularly from Australasia. Maybe you have a big collection from a specific area and can help? Ran out of time for now though - enjoy the site.
21 December 2007 - I've added a Buying/Selling page - really I'm just advertising that I'd ike to buy complete collections and wholesale lots of tektites. Also I added a Very Quick Guide - for people wanting some basic information on tektites.
20 December 2007 - Take a look at my new Tektite Localities pages. First up is a new tektite locality in Davao, Mindanao, southern-most Philippines. The tektites are not typical Philippinites, making them real interesting stuff! I've also started (but not got very far) on a page for Paracale, Bikol Region and a page for Anda, Pangasinan Region.
20 December 2007 - Xmas is nearly here and I've been destroying baubles. See the results of heating up hollow and solid glass spheres until they crack or explode! After the fun I try to apply what I've learnt to tektites. See my Bauble Destruction page. Happy Christmas everyone, and also Eid Mubarak for those celebrating Eid.
20 December 2007 - A month has passed and I've been busy enhancing the tektite reference list. Some days I've put in 14 hours - this list represents hundreds of hours of work! It now comprises 2,284 entries (I think)! There are a few more I'm sure, but this is more extensive than any others you will find and the vast majority of references relate directly to tektites. I am estimating that 700-800 are freely available on the internet and I have provided links to these. Some of the works are very enlightening. Others are interesting - one guy kept a philippinite throughout his stay in the Philippines, in a Japanese prisoner of war camp, before bringing the tektite with him to America - see Leonard, F. C. 1955 for the link.
20 November 2007 - I have made some minor adjustments to the Australasian Tektites pages and the Sculpture/Morphology pages. I was just updating these with the current thinking, particularly around the subjects of bald spots and chemical etching of surfaces resulting in enhancement of cracks. Things have to go on hold again for a couple of weeks as I'm off to work!
16 November 2007 - I heard about Kittinger's jump from 102,800 ft in 1960. I learnt that as velocity increases objects start to rotate. Many tektites clearly rotated during the ejection phase. Is there a link? I don't know, but here's the link to the 'Flat Spin' page.
16 November 2007 - See my new page Coke Can Gas. Here I am interested to try and understand what happens to gas bubbles in molten tektites when they are blasted from the surface of the Earth to high altitudes in the atmosphere, where air pressure is much lower.
15 November 2007 - A new page in the Analogues section called 'Meandering Cracks' looks into oscillating thermal crack development. This looks to be a very interesting area of research in tektites.
15 November 2007 - A new 'Tektites are Exciting' page. Convince your friends that tektites are not boring! (After 3 month's I've withdrawn this page to focus the webpage on facts - not fun!).
14 November 2007 - I have very limited time available due to work commitments, but I am full of ideas and hope to expand this site a little in the coming week. My twin brother, who is an archaeologist specialising in lithics / tool making and who can flint knap, has just earnt his Ph.D. He wants to do some joint stuff on tool making with tektites. I've set up a preliminary page on this subject - Tektite stone tools. Also I am now convinced that most tektite sculpture is due to etching. The 'weird' meandering grooves on Philippinites and billitonites might be explained by etching of oscillating thermal cracks on the glass body, formed during re-entry. Take a look at this excellent webpage: www.math.lsu.edu/~bourdin/ThermalCracks.html - more to come on this subject. I'm going to do a few experiments on household objects!
14 November 2007 - The tektite reference list now has roughly 1,850 entries! Believe it or not, a lot has been written on tektites and compilation of this list has driven me near crazy - a huge amount of work! I'm still finding more references, but this has the main ones - plus some! Now I am setting about acquiring every last one of them - any help is welcomed! If you haven't already, then take a look at the NASA Technical Server. There are many interesting papers, not just on tektites - a fantastic job. What's more US government papers are not subject to copyright as they used public funds.
03 October 2007 - More references on the reference list! This is becoming fairly comprehensive now, but I still have a lot of work to do on it, especially with regards more recent titles and more obscure tektite references. Distractions such as australite and philippinite discussion over several beers hasn't helped! I will be putting this project on hold from the 5th as I return to work for a month.
28 September 2007 - I've added some more references to the reference list. Still many days of work left though!
25 September 2007 - Yesterday we took an oxy-acetylene torch to a tektite and then to obsidian, which was rumoured to be a Moung Nong-type tektite. See what happened on the new Tektites Tests page.
21 September 2007 - I have added a Reference List and Website List page. I have added many papers to the reference list, but it is still only the very tip of the iceberg! I am beginning to wonder why I started this task... More to come!
20 September 2007 - My girlfriend Tere has asked me to put a link to her website www.filfashion.com. I'm reluctant as it has nothing to do with tektites and is therefore of little interest(!), however, if you want to find out more about Tere and I then go for it! A contents warning though - some of it is cheesy!
19 September 2007 - I have created a new page in the Analogues section called 'Cracked Glass'. This was inspired by my observation of cracked glass in a cable car in Singapore. I think this goes a long way to explaining the formation of Anda sculpture. I also look at tension gashes formed in geological shear zones. Minor updates were made to the Anda Sculpture page.
02 September 2007 - Many Australite papers received from Wayne Hitchcock in Western Australia. These were very gratefully received!
August 2007 - I updated a number of pages related to the formation of navels and U-grooves in Philippinites. It is evident that these feature form on the anterior of the tektite through loss of the stress shell: the same mechanism that forms Australite cores. Previous ideas suggesting they may form on the posterior by areodynamic processes have proven to be incorrect.
