TEKTITES, Page 2

Australites are very different is character from Indochinites as they underwent a secondary melting and are typically much smaller. To date no know location for the generating crater has not been found; but, most likely, somewhere in Asia. All of the specimens shown came from an Australian finder and have the specific location when known.
Bediasites are often discussed and much maligned. They are the oldest known of all tektites, being found in the Oligocene sediments of east central Texas, and have been dated to about 34 million years ago. Bediasites typically are typically small (1 to 5 grams) and have a near black appearance but will show some green-gray to olive-brown coloration along the thinner edges. Some are translucent. Most Bediasites are extensively worn, pitted, and have the appearance of small beans.
The most abundant source of Tektites is Southeastern Asia, especially in the countries of China and Vietnam. Tektites found in this part of the world are black, with a small percentage reaching large proportions (by tektite standards) and weights exceeding 200 grams. The shapes and surface textures provide many interesting variations. Small specimens are actually quite cheap. On the other hand, large and/or very interesting shaped specimens can command high prices. We carry small inexpensive examples for our shows but on this site we will include only larger and interesting specimens for the meteorite and tektite collector. Examples shown here are from Guangdong Province, China.
From the Philippine islands come some of the most bizarre shaped tektites known. These specimens are black and have surface markings similar to Indochinites; however, they usually have one or more deep grooves in them.
