'''Lechatelierite''' is a type of silica glass. It is an amorphous form of silicon dioxide (SiO<sub>2</sub>), lacking any crystalline structure, and is thus a mineraloid rather than a true mineral, although it is sometimes grouped with [[quartz]]. | '''Lechatelierite''' is a type of silica glass.

Lechatelierite can be formed in a number of ways. One of the most common ways that this occurs naturally is through the high-temperature melting of sand during a lightning strike; this produces a specific from of lechatelierite called "[[Wikipedia:fulgurite|fulgurite]]" which is often hollow, irregular, and tubular. Lechatelierite can also be formed through the shock metamorphosis of sand or even silica-rich rocks, such as sandstone or [[granite]], by the high pressure of meteorite impact cratering, and is thus a common component of ejecta. This form of lechatelierite is especially prevalent in the [[Wikipedia:Libyan Desert|Libyan Desert]] on [[Earth]]. Lechatelierite can even be formed by the detonation of [[nuclear weapon]]s, a phenomenon first observed following the [[Wikipedia:Trinity test|Trinity nuclear test]] in 1945. | Lechatelierite can be formed in a number of ways.

Lechatelierite is a common product of the [[Covenant]] tactic of [[glassing]], the orbital [[plasma]] bombardment of a world to render it uninhabitable. An observer offered this description: "The so-called glass is a mineral called lechatelierite. It is a result of the Covenant lances striking the surface of the planet with plasma, converting the topsoil to glass. Any attempt to make a glassed planet habitable would mean cutting the surface down to below the topsoil."<ref>''Halo 5: Guardians'', campaign level, [[Evacuation]] - Mission Intel</ref> | Lechatelierite is a common product of the [[Covenant]] tactic of [[glassing]], the orbital [[plasma]] bombardment of a world to render it uninhabitable.

Such worlds, called "the glasslands", were uninhabitable without extensive [[terraforming]]. Some, such as [[Meridian]], were sparsely covered such that they could be rehabilitated within twenty years, although others were so severely affected that terraforming efforts were projected to take upwards of a century.<ref>'''Halo 5: Guardians''', campaign level, ''[[Glassed (level)|Glassed]]'' - Mission Intel</ref> | ||

By [[2558]], the [[BXR Mining Corporation]] was involved in the commercial mining and sale of lechatelierite extracted from glassed worlds, such as [[Bliss]].<ref>[http://huntthetruth.tumblr.com/ '''HUNT the TRUTH''': ''Benjamin Giraud Entry 0384'']</ref> Such mined lechatelierite was sold in the [[inner colonies]] and converted into commodities such as housing insulation. Lechatelierite that was "organically enriched", containing carbon impurities that were the remnants of the plant, animal, and even human life of the former colonies, was especially valuable due to the [[Wikipedia:Zeolite|zeolites]] it contained. | By [[2558]], the [[BXR Mining Corporation]] was involved in the commercial mining and sale of lechatelierite extracted from glassed worlds, such as [[Bliss]].<ref>[http://huntthetruth.tumblr.com/ '''HUNT the TRUTH''': ''Benjamin Giraud Entry 0384'']</ref> Such mined lechatelierite was sold in the [[inner colonies]] and converted into commodities such as housing insulation.
