Libyan desert glass or Great Sand Sea glass is an impactite, made mostly of lechatelierite, found in areas in the eastern Sahara, in the deserts of eastern Libya and western egypt. Fragments of desert glass can be found over areas of tens of square kilomteersThe origin of desert glass is uncertain. Meteoritic origins have long been considered possible. For decades, ideas about how the glass formed included melting during meteorite impact and melting caused by an airburst from an asteroid high in Earth's atmosphere. the glass is nearly pure silica which requires temperatures above 1,600 °C to form – hotter than any igneous rock on Earth. Libyan Desert glass has been dated as having formed about 29 million years ago. Like obsidian, it was knapped and used to make tools during the Pleistocene.
