Apatite is a group of phosphate minerals, usually hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH −, F − and Cl − ion, respectively, in the crystal.
What is Apatite? Apatite is the name of a group of phosphate minerals with similar chemical compositions and physical properties. They are an important constituent of phosphorite, a rock mined for its phosphorus content and used to make fertilizers, acids, and chemicals.
Sep 25, 2023 · Apatite is a relatively common mineral that can occur in a variety of colors, including yellow, green, blue, and purple. It is an important mineral in the formation of igneous, sedimentary, and metamorphic rocks, and it can also be found in biological tissues such as bones and teeth.
Apatite is the most common phosphate mineral, and is the main source of the phosphorus required by plants. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite.
Apatite is a member of a group of structurally related minerals having compositions symbolized A5 ( B O 4) 3X, in which A is a metal, commonly calcium or lead; B is phosphorus, vanadium, or arsenic; and X is chlorine, fluorine, or hydroxyl.
'Apatite' is a field term for unidentified calcium phosphate members of the apatite group. Most 'apatite' is fluorapatite, whereas hydroxylapatite is much ...
Apatite is a superb mineral by which to investigate the nature of fluids that have passed through and altered a rock (metasomatic processes). Its ubiquity allows it to act as a reservoir for P, F, Cl, OH, CO2, and the rare earth elements.
Apatite is identified by the chemical formula Ca 5 (PO 4). It forms in hexagonal crystals and is a rock phosphate mineral. Apatite can exist in many different forms, along with other minerals, as long as the base of apatite calcium (Ca 5 ) and phosphorous (PO4) exist together.
Some minerals in the apatite group:Phosphates: Fluorapatite. Chlorapatite. Alforsite. Ellestadite.
apatite, A member of the phosphate group of minerals, the world’s major source of phosphorus, found as variously coloured, glassy crystals, masses, or nodules. Much of it has a chemical composition approximating Ca 5 (PO 4 ) 3 (F,Cl,OH).
