Fluorite formation
WebFluorite has an isometric formation, meaning the crystals develop symmetrical cubes. Thus, they are found in symmetric chunks although the corners have undergone natural wear. On the other hand, calcite develops as a trigonal hexagonal crystal system due to which many of its specimens look like a double-ended pyramid. Webfluorite crystallizing from high-temperature fluids will show a negative Eu anomaly when normalized to REY abundances of the fluid from which it crystallized.

Physical Properties Of Fluorite
Fluorite 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 it can be associated with galena, … See more Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are … See more Fluorite crystallizes in a cubic motif. Crystal twinning is common and adds complexity to the observed crystal habits. Fluorite has four perfect cleavage planes that help produce octahedral fragments. The structural motif adopted by fluorite is so common that the … See more Fluorite is allochromatic, meaning that it can be tinted with elemental impurities.
