Fluorite comes from the remains of volcanic magma. During the cooling process of magma, the gas-water solution separated from the magma contains many substances, mainly fluorine. During the rising process of the solution along the crack, the temperature decreases, the pressure decreases, and the fluorine ions in the gas-water solution combine with the calcium ions in the surrounding rocks to form calcium fluoride. After cooling and crystallization, fluorite is obtained.

Fluorite comes from the remains of volcanic magma. During the cooling process of magma, the gas-water solution separated from the magma contains many substances, mainly fluorine. During the rising process of the solution along the crack, the temperature decreases, the pressure decreases, and the fluorine ions in the gas-water solution combine with the calcium ions in the surrounding rocks to form calcium fluoride. After cooling and crystallization, fluorite is obtained.
Fluorite ore is a accessory mineral in granite, pegmatite and syenite. Fluorite can be found in carbonatite, alkaline intrusive rock and near the fumaroles around the volcano. It is also deposited in hydrothermal veins and stratabound deposits. At the natural joint of sandstone, fluorite will act as an adhesive.
Most fluorite crystals are octahedral and cubic, and rarely dodecahedral crystals. There are also composite crystals formed by intersection of octahedron and cube. Cleavage traces are present on most crystals, and cleavage blocks peeling off from larger crystals are also common.
Under octahedral crystallization, the cleavage block is flat and triangular; The cleavage block of cubic crystal is a flat cuboid. The crystals of fluorite often have interpenetrating double crystals, that is, double crystals formed by two crystals penetrating each other. There are also symbiotic cubic crystals formed by clusters, or granular, grape, spherical or irregular blocks.
