1.65" Indochinite Tektite (17.2 grams) - Pailin District, Cambodia

Indochinite tektites are some of the best known of the tektites. They are often found in teardrop, round, and cigar shapes throughout the Thailand, Cambodia, Laos, and Vietnam area. The composition of these tektites is roughly 70-80% SiO2.

Tektites are formed when a huge meteorite collides with the Earth with such force that melted rock and meteorite are thrown at high speed into the upper atmosphere. Here they cool and harden, preserving their splash-like, melted shape. Tektites are found in strewn fields sometimes thousands of miles across.
