Pyrochlore, apatite and rare earth-bearing minerals are typically the most sought after mineral constituents, however, a wide variety of other minerals including magnetite, fluorite, calcite, bornite, chalcopyrite and vermiculite, occur in economic concentrations in at least one carbonatite complex

"The mineralogic, geologic, and structural features of the veins1 are such as to support the idea of deposition largely or entirely from waters of low temperature, possible of meteoric origin, though scarcely of pronounced artesian circulation

(3) For each period of geologic time, the discussion of stratigraphy will proceed counterclockwise around the perimeter of the Delaware Basin, from the northwest (Guadalupe Mountains) to the west, south, east, and north; then basinal rocks of the same age will be discussed (4) For each period of geologic time where there is a
Fluorite-quartz vein deposits also occur in the St Peters Dome area, and were once mined for fluorite Classic papers on the Mount Rosa area are those by Gross and Heinrich (1965, 1966a,b), and a recent excellent paper is that by Zito and Hanson (2014) about Stove Mountain
A relationship between plagioclase composition and fluoride concentrations suggests that dissolved fluoride levels are controlled by fluorite solubility and that higher fluoride concentrations are found in soft, sodium-rich groundwater

Cleavage exhibited on a horizontal plane of the mineral by way of its base Minerals with basal cleavage can sometimes be "peeled" An , An example is Fluorite Prismatic cleavage: Cleavage exhibited on some prismatic minerals in which a crystal cleaves as thin, vertical, .
In places, the fluorite content diminishes with depth and its place is taken by calcite The vein material probably was formed through two processes of deposition: (1) vein filling and (2) replacement of brec- ciated calcareous vein material and wall rock The tabular, horizontal ,

This assumption is supported by the close association of the opaline silica with fluorite and the presence of silica in hot-spring deposits elsewhere at Lake Bogoria (Renaut and Owen, 1988, Renaut and Jones, 1997)
Dulski, 1995），Fluorite(Ⅰ) and fluorite(Ⅱ) are roughly on a horizontal line，which suggested that they are homogenous products at different generations in combination with its geologic features；And the fluorite (Ⅲ) is on another horizontal line different from the fist two generations，indicated that it has a different source 2+

Economic Geology Fluorite, zinc, lead, and barite have been mined at several surface pits and underground mines in this quadrangle Mineralization within the Illinois-Kentucky Fluorite District probably results from an acidic brine, charged with fluorine and carbon dioxide gases derived from alkaline magma (Plumlee et al 1995)

Introduction Fluorite deposits are formed by various processes under different physicochemical conditions in a range of geologic settings These deposits are mostly of two lithologic types: (1) those in sedimentary rocks, dominantly carbonates; and (2) those found as veins in, or associated with, dominantly alkaline–peralkaline igneous rocks that are akin to magmatic-hydrothermal vein-type .
Geology Fluorite Mineral Resources • Fluorite Mineralisation in the Peak District orefield is contained within a series of near vertical veins hosted in limestone from the Carboniferous period • Hydrothermal mineral enriched veins are formed in the cracks of fissures within the limestone fault systems
