  • Fluorite and Fluorspar: Mineral uses and properties

    Fluorite is deposited in veins by hydrothermal processes. In these rocks it often occurs as a gangue mineral associated with metallic ores. Fluorite is also found in the fractures and cavities of some limestones and dolomites. It is a very common rock-forming mineral found in many parts of the world. In the mining industry, fluorite is often

    The fluorite here is primary, as it occurs as euhedral and subhedral single crystals in a relatively fine-grained matrix. It has high negative relief, its refractive index being considerably lower than adjacent quartz and feldspar, and epoxy. Sodalite has much less pronounced relief and poorer cleavage. Fluorite, of course, is isotropic.

    Sep 01, 2000· The bedrock geology in the vicinity of the Long Lake calcite-fluorite veins is complex, consisting of a number of structurally deformed sedimentary and igneous rocks that have been metamorphosed to granulite facies. The calcite-fluorite vein occurrence itself is hosted by one such unit of granitic gneiss.

    The veins are nearly vertical and the walls as a rule are clean cut but this is varied by replacement, brecciation, and the mineralization of small fractures in the wall rock. There is great variation in width horizontally and with depth in the same veins. The Hayden vein, one and a half miles south of Danville, is eight to 14 feet wide.

    The veins occupy fault-fractures with strike lengths of several kilometres and typically reveal ribbonlike textures as in the example illustrated above. Metamorphic reactions causing widescale dewatering of deeply-buried rocks is believed to have been the mechanism which generated the hydrothermal fluids.
