Abstract
Ever since the discovery of Libyan Desert Glass in the southwest corner of the Great Sand Sea near the Libyan border, its source of formation has become the subject of controversy that still has not been resolve. This paper introduces a general description of Libyan Desert Glass. It presents briefly different theories explaining its formation. This paper introduces also new interpretation for Libyan Desert Glass formation. This interpretation suggests a meteorite impact mechanism. In this paper, the study of meteorite impact mechanism of BP and Oasis craters was carried out for the first time using a simple model. Calculations have shown that change in temperature for the target materials (sand) because of meteorite impact could explain the formation mechanism of Libyan Desert Glass that took place about 29 million years ago.
