Fluorite, also called fluorspar, common halide mineral, calcium fluoride (CaF2), which is the principal fluorine mineral. It is usually quite pure, but as much as 20 percent yttrium or cerium may replace calcium. Fluorite occurs most commonly as a glassy, many-hued vein mineral and is often associated with lead and silver ores; it also occurs in cavities, in sedimentary rocks, in pegmatites, and in hot-spring areas

Tanzanite is a captivating gemstone known for its striking color and rarity. It is a variety of the mineral zoisite and exhibits a unique...

Kyanite is commonly found in aluminum-rich metamorphic pegmatites and / or sedimentary rocks and is commonly a blue silicate mineral. Cyanide in metamorphic rocks show better pressures than four kilobars. Although it is undoubtedly strong at stress and low temperature, it is generally sufficiently high under these conditions where water hobbyist, muscovite, pyrophyllite or kaolinite-containing aqueous aluminosilicates are replaced. Kyanite is also called disten, ranetite and cyanide.

Calcite is a rock-forming mineral with a chemical formula of CaCO3. It is extremely common and found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere.

The principal ore of antimony, stibnite is antimony sulfide. Its name comes from the Latin stibium. Lead-gray to silvery gray in color, it often develops a black, iridescent tarnish on exposure to light. It normally occurs as elongated, prismatic crystals that may be bent or twisted.

The pyroxenes are a set of essential rock-forming inosilicate minerals discovered in many igneous and metamorphic rocks. Pyroxenes have the general components is XY(Si,Al)2O6.Although aluminium substitutes extensively for silicon in silicates consisting of feldspars and amphiboles,

Five percent of Earth’s crust is made up of iron. Native iron is rare in the crust and is invariably alloyed with nickel. Low-nickel iron (up to 7.5 percent nickel) is called kamacite, and high-nickel iron (up to 50 percent nickel) is called taenite. Both crystallize in the cubic system. A third form of iron-nickel, mainly found in meteorites and crystallizing in the tetragonal system, is called tetrataenite. All three forms are generally found either as disseminated grains or as rounded masses. Kamacite is the major component of most iron meteorites. It is found in most chondritic meteorites, and occurs as microscopic grains in some lunar rocks. Taenite and tetrataenite are mainly found in meteorites, often intergrown with kamacite. Iron is also plentiful in the Sun and other stars.
