Tektites (from Greek ‘tektos’, molten) are natural glass objects that were formed by the impact of large meteorites on Earth’s surface. Tektites are the driest minerals known, with an average water content of 0.005%. This is very rare, since most of the craters where tektites formed were underwater before the impact. Besides, partially melted zircon has been found inside some tektites. This, together with their water content, suggests that tektites formed under very high temperature and pressure conditions (similar to those necessary to form diamonds). Indochinites like the one in this lot were formed by the impact of a large meteorite 800,000 years ago, according to the most recent studies. The impact was brutal, so molten material covered 10% of the Earth’s surface and indochinites have been found even in Antarctica. The specimen in this lot is natural and has a large size.
