The fluorite here is primary, as it occurs as euhedral and subhedral single crystals in a relatively finegrained 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.

Vein deposits of this nature are a type of hydrothermal deposit because the mineral species which compose the veins were precipitated by hot waters. However, sometimes the preexisting rock wall which contains the vein undergoes alteration. Portions of the host rock may either dissolve and be transported away or else react chemically with the circulating volatile fluids or the newly formed ...

Epigenetic fluorite deposits commonly coincide with regions of low gravity and zones of high heat flow, igneous activity, and hydrothermal effects . [16] Tectonic environments consist chiefly of tensional and deepseated normal fault zones. The fluorite deposits in the world most commonly occur as veins.
There it occurs as vein deposits and as a disseminated replacement mineral in the region''s widespread Paleozoic carbonate rock layers. Pyrite is also found along the Canadian border, in massive sulfide vein deposits of the middle and late Precambrian volcanic rocks of northern Wisconsin and northern Minnesota where it is associated with ...

Fluorite is a halide mineral that is soft and usually colorless but can be blue, purple, green, brown, or yellow. Some times several colors are present in the same crystal creating a striking affect. Fluorite forms crystals in the isometric system, typically cubic crystals, though octedral, or eight sided, crystals are also common.

Fluorite is a mineral that mostly occurs in hydrothermal veins. The chemical composition is very simple: CaF is not very common mineral because fluorine (F) makes up only % of the mass of the crust and there are other minerals also that want fluorine into their crystal structure.
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.

fluorite, and danalite(?) also coat small open fractures in the Conway Granite. Solutions rising from deeply buried parts of the Conway Granite plutons are believed to have caused mineralization of the chilled outer zones and to have formed all the breccia veins of the group. INTRODUCTION
COUNTY: Fluorite occurs as rare purple vein fillings in the Alders quarry, on Highway 151 on the north edge of Alders (Carl Cochran, 1999, personal communication). MARATHON COUNTY: Fluorite is a common component of the igneous rocks around Wausau. Fluorite is a widespread common accessory in the Nine Mile granite (Patton et. al., 1989).
Bristen granite is a body of finegrained leucogranite occurring in the Gotthard rail base tunnel in the Central Alps. During construction of the tunnel, Bristen granite (Brgr) has been drilled along a 600nbsp;m long section. The aplitegranite belongs to the suite of Variscan granitoid intrusions of the Aar massif and contains a variety of accessory minerals typical of highly differentiated ...
Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth''s crust. Learn more about the structure, properties, and uses of dolomite in this article.
The veins occupy faultfractures with strike lengths of several kilometres and typically reveal ribbonlike textures as in the example illustrated above. Metamorphic reactions causing widescale dewatering of deeplyburied rocks is believed to have been the mechanism which generated the hydrothermal fluids.
Fluorite is the only mineral for which significant quantities of the important element fluorine can be obtained. Fluorite is also used as a flux in the manufacture of steel and other metals to eliminate is a great demand for Fluorite in the optics field, and to meet it synthetic crystals are grown to produce special lenses.
Epigenetic fluorite deposits commonly coincide with regions of low gravity and zones of high heat flow, igneous activity, and hydrothermal effects . [16] Tectonic environments consist chiefly of tensional and deepseated normal fault zones. The fluorite deposits in the world most commonly occur as veins.
The fluorite veins considered as lowtemperature deposits (Zou et al., 2020a).
