Tektite

This page is currently not sponsored. Click here to sponsor this page.
A natural glass formed from a meteorite impact melting the local rock. Depending on the nature of the latter, the composition of tektites is variable. Hence, many varietal names are given to tektites from different localities.

The meteoritic source was determined for three fields of scattered tektites (bediasite and georgiaite in North America, moldavite in Central Europe, and ivorite in West Africa). Though, for Australian and Asian tektites (indochinite, australite, zhamanshinite, irghizite, and others), the occurrence in meteoritic craters has only been inferred.
