Libyan Desert Glass is a tektite- silicated glass formations whose name comes from the Greek tektos, meaning “melted”. They are the result of an asteroid slamming into and melting the Earth’s surface; the extraordinary heat and pressure liquefies terrestrial rocks, which are splashed into the upper atmosphere before returning to Earth as solidified glass. This occurred approximately 28.5 million years ago in the southwestern corner of the Great Sand Sea near the Egyptian/Libyan border.
