a common mineral, calcium fluoride, CaF 2 , occurring in green, blue, purple, yellow, or colorless crystals, usually in cubes: the principal source of fluorine, used also as a flux in metallurgy and for ornament.
The seeming disorder of calcite highlights the geometric precision of fluorite.
Distal barite-fluorite veins consist of variable proportions of barite, fluorite, and manganese oxides.
fluorite is a bluish-green mineral used in the smelting of iron and in the ceramic and chemical industry.
