Apatite is the name given to a group of phosphate minerals that are widely distributed in all rock types, usually in tiny crystals spread throughout the host rock. { The apatite group minerals belong to the apatite super-group (Pasero et al., 2010) with a chemical formula of M1 2 M2 3 (TO 4) 3 X and include hexagonal and pseudohexagonal phosphates, arsenates, and vanadates containing the same dominant element in the M1 and M2 sites, and having P, V, or As in the T site. Mindat.org's Discussion Groups { Chemistry: Ca5(PO4)3(OH,F,Cl), Calcium (Fluoro, Chloro, Hydroxyl) Phosphate Class: Phosphates; Group: Apatite; Uses: as a source of phosphorous to be used in fertilizer, rarely as a gemstone and as a mineral specimen. Hydroxyl endmember of the complex apatite group.

Apatite has a relatively consistent hardness and serves as the index mineral for a hardness of five in the Mohs Hardness Scale. Hammers, Chisels, Loupes, Cotton-filled boxes, etc. The most common ones are fluoro-apatite, the lesser color apatite and the hydroxyl-apatite minerals. Some specimens are multicolored. Hexagonal apatite crystals are sometimes found in igneous and metamorphic rocks. Also known as Carbonate-rich Apatite. quartz).

The other two common minerals of the apatite group are chlorapatite and fluorapatite. Original Rockhounds Discussion Group Apatite is the main source of phosphate that is mined industrially . The phosphorous in apatite (notice the "P" in the formula) makes this mineral family an important fertilizer. { Because apatite stone types are easily mixed with other minerals in appearance. It is one of a few minerals produced and used by biological micro-environmental systems. These minerals are all calcium phosphates, differing from one another chemically only in that fluorapatite contains fluorine; chlorapatite, chlorine; hydroxylapatite, a hydroxyl (OH) group; and carbonate-apatite, a carbonate (CO 3) group. Apatite Mineral Facts: Chemical Formula: Ca 5 (PO 4) 3 (OH,F,Cl) Phosphate and fluoride of calcium, or phosphate and chloride of calcium ; the first being fluorapatite, Ca 5 (PO 4) 3 (F), the second chlorapatite, Ca 5 (PO 4) 3 (Cl).Usually some amounts of both chloride and fluoride are present together. I - Indicies Apatite is characteristic of biological systems. Apatite is mineral group with the following chemical formula applied to the most common members of the primary group (excluding the extended Apatite supergroup): Colorless, white, yellow, brown, gray, red, pink, purple, blue, green.
