These true North American tektites were formed by the asteroid impact that created the Chesapeake Crater around 35 million years ago. The rarity of these tektites is mainly attributable to the fact they are buried! Only where the correct age rock is exposed and the tektites are weathered out are they found.

Georgiaites, found in Georgia, USA, include moung Nong types and splashform types. They are extremely rare and are found in the order of 700km southwest of the Chesapeake source crater. For a good example see page 139 of Povenmire, 2003.

For Geogiaites check out the Meteorite Association of Georgia tektite webpage. It's fantastic!


ABOVE:   A 20.2g Georgiaite currently (July 2007) for sale at Thanks to Paul Harris for permission to use this photo. You will note the apparent starburst rays seen on this specimen. Compare these with starburst rays seen on Indochinites (this one is from Thailand). This tektite feature is highly typical of proximal splashforms and was likely formed when the semi-molten tektite struck the ground.

ABOVE:  An 11.5g teardrop Georgiaite. This was found by George Bruce in the 1950/60's and is now in my collection

Bediasites, found in Texas, USA, include very rare large forms that look remarkably like large breadcust Bikolite-type Philippinites (see page 150, Povenmire, 2003). Furthermore, the smaller specimens are not dissimilar to smaller Philippinites. V-shaped grooves, similar to Anda and Moldavite sculpture are also observed in Bediasites and is almost certainly due to chemical etching in the ground. Interestingly Bediasites occur about 1800km from the Chesapeake source crater. The Bikolite-type tektites and Philippinite biscuits are an estimated 1600km to 2000km from the likely source crater locations. Excellent images of Bediasites can be found on The Tektite Source website.

The images below were sent to me by Brian C Burrer. I feel honoured to be able to place these rare images on my page, allowing comparisons to be drawn with other tektites. Brian Burrer is a hunter/collector of tektites and related material. In the last seventeen years Brian has been fortunate enough to recover over seven hundred specimens of Bediasites as well as one Georgiaite on a trip to Georgia. Brian is currently focusing on expanding the strewn fields of Bediasites and Georgiaites.

ABOVE:   Teardrop Bediasites from Brazos County, Texas. From left 18.9g, 6.2g and 12.7g. A 23mm diameter Euro coin is used for scale. Many thanks to Brian Burrer for this photo.

ABOVE:   Six well featured Bediasites from Brazos County, Texas. Clockwise from top center 42.2g, 36.7g, 27.0g, 27.5g, 37.8g and 26.5g. A 23mm diameter Euro Coin is used for scale. Many thanks to Brian Burrer for providing this photo of his wonderful collection. The top right (36.7g) specimen appears very similar to some biscuit-form Philippinites. The top center specimen (42.2g) and others show similarity to some Anda subtype III (Beyer's Pangasinan type).

ABOVE:   Four Bediasites from Brazos County, Texas - rods and bubbles. From top center 16.7g, 20.3g, 10.9g and 21.0g. Thanks to Brian Burrer for this photo of his collection.

ABOVE:   Five Bediasites from Grimes County, Texas. Clockwise from top center 30.0g, 13.6g, 10.7g, 15.4g and 8.4g. Thanks to Brian Burrer for this image of his collection. Compare the bottom left specimen (15.4g) with an biscuit-shaped Anda subtype III tektite from Pangasinan, Philippines.


A tektite has also famously been found at Martha's Vineyard, some 1000km to the northeast of the Chesapeake source crater. This was similar to the Georgiaites.

It has also been reported that a tektite was found in Cuba. This is in the order of 1700km to the south of the Chesapeake source crater.

It is interesting to compare these North American tektites, where the source crater is well established, with the Australasian strewnfield where a crater has yet to be found. Additionally, comparisons of surface sculpture with Australasian tektites may help to understand the formation and subsequent weathering/etching of tektites.
