Tektites are formed when meteors collide with Earth. The material ejected from the impact crater is heated and fused into glass. This batch of tektites are from the Australasian st rewn field, which covers the area within the blue region in the map below and is estimated to have been caused by an impact 790,000 years ago. All Australasian tektites have a similar chemical composition, which is why they are thought to be from the same impact. The location of the impact crater is still unknown, but a recent study suggests it may have been discovered in Laos. You will receive one Australasian tektite. All are ~1-2 cm. Some have smooth concave surfaces formed by air pockets. Color is nearly opaque black. The photos are an average representative of our current inventory. You may not receive these exact specimens, but some like them. We try to prioritize the largest specimens to ship first. Image: Meteor Crater Show more
