    en.wikipedia.org/wiki/Trinitite

    Trinitite, also known as atomsite or Alamogordo glass, [1] [2] is the glassy residue left on the desert floor after the plutonium-based Trinity nuclear bomb test on July 16, 1945, near Alamogordo, New Mexico. The glass is primarily composed of arkosic sand composed of quartz grains and feldspar (both microcline and smaller amount of plagioclase ...

    Libyan desert glass A large sample with mass 26 kg. Exhibited at the National Museum of Natural History in Paris in 2018.. Libyan desert glass or Great Sand Sea glass is an impactite, made mostly of lechatelierite, [1] found in areas in the eastern Sahara, in the deserts of eastern Libya and western Egypt.

    Such current may propagate into silica-rich quartzose sand, mixed soil, clay, or other sediments, rapidly vaporizing and melting resistant materials within such a common dissipation regime. [3] This results in the formation of generally hollow and/or vesicular, branching assemblages of glassy tubes, crusts, and clumped masses. [4]

    The Atacama Desert in northern Chile is one of the driest places on Earth, but it is not the weather that has left scientists puzzled, but the glass that is scattered across a large region of the ...

  6. Lechatelierite - Wikipedia

    en.wikipedia.org/wiki/Lechatelierite

    One common way in which lechatelierite forms naturally is by very-high-temperature melting of quartz sand during a lightning strike. The result is an irregular, branching, often foamy hollow tube of silica glass called a fulgurite. [2] Not all fulgurites are lechatelierite; the original sand must be nearly pure silica.

    en.wikipedia.org/wiki/Glass

    Trinitite is a glassy residue formed from the desert floor sand at the Trinity nuclear bomb test site. [19] Edeowie glass, found in South Australia, is proposed to originate from Pleistocene grassland fires, lightning strikes, or hypervelocity impact by one or several asteroids or comets. [20]
