Tektites are natural objects, which have been formed by the impact of large meteorites on Earth's surface. Tektites are among the "driest" rocks. They appear black, but when held up to the light, you can sometimes see a golden tint in translucent areas around the edges. Its slightly worn surface is pitted with tiny aerodynamic holes. Thailand tektites are known as “Indochinite” which have been shown by K-Ar radiometric age dating to be approximately 700,000 years old.
Scientists believe that the tektite's origin is the result of meteorite impact on either terrestrial or lunar rocks. The tektites then formed when molten rock, created by the meteorite's hyper-velocity impact, flew through the air hardening into natural glass with aerodynamic forms and surface features. Beautiful, black, shiny, and well-formed might all be descriptive words that apply very well to the splash form tektites found in Thailand.
Discovery: Indochinite Tektite or Thailandite has had been the tektites; it almost found in Thailand Northeast until to Lao and also Vietnam area. But these tektites found in Thailand which it has a unique, format, a variety of skin; that has much more collection.
