Wikipedia
Tektites (from Greek τηκτός tēktós, "molten") are gravel-size bodies composed of black, green, brown or gray natural glass formed from terrestrial debris ejected during extraterrestrial, meteorite impacts. They generally range in size from millimeters to centimeters. Millimeters-size tektites are known as microtektites.
Tektites are characterized by:
- a fairly homogeneous composition;
- an extremely low content of water and other volatiles;
- an abundance of lechatelierite;
- a general lack of microscopic crystals known as microlites and chemical relation to the local bedrock or local sediments;
- their distribution within geographically extensive strewnfields
