This It is believed that natural glass found in thousands of square miles in Western Egypt is from one of two events: either a meteorite impact on the earth's surface or an air blast, an explosion that occurs, when a space rock penetrates the atmosphere of our planet.

A new study suggests that it is the former. The glass once contained pieces of a rare "shocked" mineral called Reidite, which only forms during a meteorite strike, researchers from Australia and Austria reported on May 2 in the journal Geology.

The heat generated either by the meteorite impacts or a blast of air would have been enough to liquefy the sand in the desert and produce the glass particles. But while air blasts in the air generate shock waves that can amount to thousands of pascals (a pressure unit), asteroid collisions cause shock waves of billions of pascals on the ground, the researchers wrote. (In other words, meteor impacts create shockwaves that exert millions of pressure over air blasts.)

These ground-based shockwaves, but not the blasts of air, are strong enough to produce reidite.

In the new study, the researchers analyzed grains of mineral glass found in the glass; The scientists found that it contained evidence of the earlier presence of reidite.

In other words, its constituents are oriented to indicate a unique reidite that has been converted to zirconium at one point. This is the first "clear" proof that the glass was created by high-pressure shock waves and thus by a meteorite impact, the researchers wrote in the study.

"Meteor impacts are catastrophic events, but they are not common." Co-author Aaron Cavosie, a senior researcher at Curtin University in Australia, said in a statement. "Airbursts are more common, but we now know that we can not expect a glassmaking event in the Libyan desert in the near future, which is a bit of comfort."
