Fluorite, or calcium fluoride (CaF2), is a simple halide commonly occurring as a glassy, hued,
vein in a variety of mineral environments. It is commonly found in metallic hydrothermal deposits
associated with lead, silver, galena, sphalerite, cobalt and other economic minerals.
It also occurs in cavities of pegmatites, in hot-springs areas and in sedimentary rocks,
primarily limestones that have been permeated by aqueous fluoride.

Fluorite is found worldwide in China, South Africa, Mongolia, France, Russia, and the central North America. Here, noteworthy deposits occur in Mexico, Illinois, Missouri, Kentucky and Colorado in the United States.
