Lot 751
Set of Four Major Shapes of Indochinite Tektites. Tektites are glass-like objects that formed when a very large meteorite impacted the earth vaporizing itself and melting earth rocks to over 2000 degrees. The black Indochinites are found mostly in and around Thailand and are a glossy black color made up of mostly amorphous silica somewhat resembling obsidian. They have been dated to be about 800,000 years old which would be the date of the meteorite impact.when they formed out of the molten earth and meteorite. As the molten rock solidifies into small objects, if there is no rotation it will form a sphere, a slow rotation will form a flattened disc, fast rotation will form a rod or dumbell shape and a very fast rotation will form a teardrop shape. These four examples of formation are contained in a 8 x 6" Riker mount. Estimate Value $300 - UP
