High-silica glass (SiO2) found in western Egypt near the Libyan border. The glass is often worn smooth due to aeolian sandblasting and ranges in color from milky white to the gem quality translucent yellow-green. The glass often contains small bubbles and An amorphous silica glass formed naturally by the heat of impact/detonation of a large meteorite on/over quartz sand. Lechatelierite is found as an inclusion in Libyan Desert Glass. Most commonly formed during lightning strikes in sand. Named for Henry Louis Le Chatelier (1850-1936), a French chemist.. The origin of the glass is still disputed, but a How long Sonic booms Of the several 10s of tons of cosmic material entering Earth's atmosphere each day, only about one ton reaches the surface. An object's chance of survival depends on its initial mass, speed and angle of entry, and friability (tendency to break up). Micrometeoroids radiate heat so impact seems to be the most accepted explanation.
