Gravel-sized glassy bodies of natural glass formed from terrestrial debris ejected during large impacts.

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.

Varieties of TektiteHide

AustraliteA tektite variety from the Australasian strewnfield.
Dark, mostly black.
BediasiteA black tektite variety from North American strewnfield (Chesapeake Bay impact crater), found in Texas, USA.
BikoliteA name given to tektites from the Bikol area of the Philippines.
BillitoniteA tektite material found on Billiton Island, between Sumatra and Borneo.
Compare indochinite.
ChiniteA black tektite variety from the Australasian strewnfield.
Found in China, hence the name.
Darwin GlassFrom Tasmania, Australia.
GeorgiaiteA green tektite variety from North American strewnfield (Chesapeake Bay impact crater), found in Georgia, USA.
IndochiniteA tektite variety from the Australasian strewnfield.
Dark, mostly black.
IrghiziteTektite (only?) from the Zhamanshin meteor crater in Kazakhstan (latitude: 48° 24' North, longitude: 60° 58' East).
IvoriteA black tektite variety from the Ivory Coast strewnfield (Lake Bosumtwi Crater, Ghana).
Found in the Côte d'Ivoire (Ivory Coast).

NOTE: Some tectites from the large Australasian field are fraudulently sold in Ivory Coast as being Ivory Coast tektites...
ZhamanshiniteTektites from the Zhamanshin meteor crater.
