Libyan Desert Glass

Libyan desert glass is a type of tektite/impactite, a yellowish natural glass mineral that forms when silica is exposed to extreme heat and pressure. Libyan desert glass may have formed when a meteor shower imapcted the Sahara Desert nearly 29 million years ago. For many years scientists have believed that the mineral was the result of an extremely large air-blast, roughly 100 megatons, caused by an explosion in space near Earth’s atmosphere. After extensive analysis, scientists discovered that Libyan desert glass was indeed created by meteor impacts.
