Basics of Mineralogy - West ia University

Chemical Composition of Minerals Many minerals have a precise chemical formula. Examples include: quartz, SiO2 calcite, CaCO3 Other minerals have a variable formula because of ionic substitution, which does not change crystal structure. Examples include: olivine (Mg, Fe)2SiO4 pyroxene (Mg, Fe)SiO3 plagioclase NaAlSi3O8 or CaAl2Si2O8

As an example, for centuries the Chinese mined a green variety of fluorite, erroneously called 'green quartz', for carvings and figurines. Clear fluorite is among the rarest of the many fluorite varieties and was once used in the manufacture of optical lenses.

Fluorite: Mineral information, data and localities.

Fluorite is found as a common gangue mineral in hydrothermal veins, especially those containing lead and zinc minerals. It is also found in some greisens, granites, pegmatites and high-temperature veins, and as a component of some marbles and other metamorphic rocks.

Fluorite, also known as Fluorspar and Fluor Spar

Fluorite is a popular gemstone appreciated by crystal enthusiasts and many alternative therapists. Fluorite is mined in many places around the world and may be found either alone or together with metallic ores and other minerals such as baryte, calcite, celestine, quartz and topaz.

FLUORITE – Mardani Fine Minerals

This example is a brilliant, richly saturated, golden yellow with an intense, glassy luster. This stunning yellow fluorite is punctuated by a second generation of smaller, flattened fluorites with a deep magenta coloration. The combination of these two colors is both visually arresting and geologically rare.

Fluorite - an overview | ScienceDirect Topics

Fluorite. Fluorite [CaF2] is a common accessory mineral in many hydrothermal ore deposits, and its dissolution can release F. The dissolution of some layered silicates, such as biotite, can also release F. Fluorite is the least soluble F-containing mineral that might be expected to form and limit F concentrations in low temperature systems.

The Differences Between Fluorite & Calcite | Sciencing

Fluorite and calcite, two mineral types, are vastly different in shape and behavior. For example, fluorite grows using a symmetrical crystal system, while calcite forms asymmetrically. Calcite is considered a common mineral, while fluorite is a semiprecious mineral. The two are found in vastly different environments and locations throughout the ...

Taolin Zn-Pb-fluorite deposit, People's Republic of China ...

The ore in this large Zn-Pb-fluorite deposit in NE Hunan Province occurs as open space-filling in a major fault zone between granite and metasedimentary rocks. Following barren, pre-ore quartz, three stages of ore deposition are recognized. Studies on 400 fluid inclusions from all four stages show homogenization T of 120-200oC (av. approx 160o) and salinities of 0-14 wt.% equiv. NaCl (av. 7.7) .

Color

The problem is shown to the left, in which the mineral fluorite (CaF 2) displays a rainbow of colors. Some minerals do have only a single color that can be diagnostic, as for instance the yellow of sulfur. Also, although many minerals vary in color few span the spectrum of colors as fluorite does.
