Libyan Desert Glass

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 lechatelierite. The origin of the glass is still disputed, but a meteor impact seems to be the most accepted explanation.
