The origin process of lechatelierite
Pyro-quartz has three different origins: meteorite impact, volcanic activity and lightning strike.
The very strong pressure produced by the meteorite impact melts the quartz particles in the rock it hits; the origin of the volcano is the same as the formation of obsidian, and the lava cools too quickly to form a crystal structure. But obsidian is generally mixed with various chemical substances in addition to SiO2; the origin of lightning strikes is perhaps the most interesting. When lightning strikes sandy areas on the earth such as deserts or beaches, the intense heat and energy of lightning will melt in a millisecond Sand grains often form a branched, hollow, glass-like tube. These "fossil" lightnings are made of pyro-quartz, sometimes with biotite and other minerals. They are called lightning lava and are a natural historical miracle. The lightning lava found was a few feet long, although most were several inches long and half an inch thick.
