    OverviewOccurrence and miningHistory and etymologyStructureFluorescenceColorUsesImages

    Flourite forms as a late-crystallizing mineral in felsic igneous rocks typically through hydrothermal activity. It is particularly common in granitic pegmatites. It may occur as a vein deposit formed through hydrothermal activity particularly in limestones. In such vein deposits is can be associated with galena, sphalerite, barite, quartz, and calcite. Flourite is can also be found as a constituent of sedimentary rocks either as grains or as the cementing material in sandstone.
