F - Fit to Screen apatite A widely distributed phosphate mineral, with the formula Ca 5 (PO 4) 3 (F,Cl,OH); sp. 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 Treatments; Some violet apatite turns green on exposure to radium (Przibram and Caffyn, 1956) and violet apatite which has lost its color from heating (perhaps to 500°C) is turned partly green and partly violet; there is no effect of electrons and only a minor effect of X-rays on some yellow and green specimens (Pough and Rogers, 1947; Pough, 1957) – Nassau (1984) Link to MinDat.org Location Data. Hydroxyl endmember of the complex apatite group. Apatite is the defining mineral for 5 on the Mohs scale. It can form large crystals in contact metamorphic rocks. Renamed in 1860 from the original apatite of Abraham Werner by Carl F. Rammelsberg to emphasize the chemical composition. Apatite is now a group name for a series of related minerals. 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.

The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite. Apatite is found in small amounts in all kinds of rocks--from those cooled from boiling lava to those formed from compacted grains of sand. { Apatite is a member of a group of structurally related minerals having compositions symbolized A 5 (BO 4) 3 X, in which A is a metal, commonly calcium or lead; … Also known as Carbonate-rich Apatite. 1 Mine, Groton, Grafton Co.
