The origin of desert glass is uncertain. Meteoriticorigins have long been considered possible, and recent research links the glassto impact features, such as zircon-breakdown, vaporized quartzand meteoritic metals, and to an impact crater.Some geologistsassociate the glass with radiative meltingfrom meteoric large aerial bursts.making it analogous to trinititecreated from sandexposed to the thermal radiationof a nuclear expolsionLibyan Desert glass has been dated as having formed about 29 million years ago.Like obsidianit was knappedand used to make toolsduring the Pleistocene. The glass is nearly pure silica which requires temperatures above 1,600℃ to form – hotter than any igneous rock on Earth. However, few mineral relics survived from whatever caused the melting, including a form of quartz called Cristobalite -a rarely occurring high-temperature mineral, and grains of the mineral Zircon– although most have reacted to form a higher-temperature mineral called Zirconia.Ideas about how the glass formed include melting during meteorite impact, or melting caused by an airburst from an asteroid or other object burning up high in Earth’s atmosphere.
