The formula of the admixture of the three most common endmembers is written as Ca10(PO4)62, and the crystal unit cell formulae of the individual minerals are written as Ca10(PO4)6(OH)2, Ca10(PO4)6F2 and Ca10(PO4)6Cl2. The mineral was named apatite by the German geologist Abraham Gottlob Werner in Apatite, Phosphorite and Phosphate Rock Physical Properties. Apatite is best known for its use as an index mineral with a hardness of 5 in the Mohs Hardness Geologic Occurrence. Apatite forms under a wide variety of conditions and is found in igneous, metamorphic, and Phosphate Rock and The apatite Mineral Group 1) Specimens from certain localities will fluoresce orange yellow in shortwave ultraviolet light. 2) Thermoluminescent bluish-white.

Apatite is a generic name, first introduced in the mineralogical literature by Werner (1786), and used to describe calcium phosphates with simplified formula Ca 5 (PO 4) 3 X (X = F, Cl, OH). The name originates from the Greek απατάω, which means “to deceive”, because the mineral was often mistaken for other species (Fig. 1 1).Since 1856–1860, these minerals have been named Apatite is generally a group of phosphate minerals consisting of high concentration of OH−, F − and Cl − referred to as hydroxylapatite, fluorapatite and chlorapatite respectively. Actually, it is a type of mineral named by German geologist in 1786. Apatite is the most commonly used mineral especially in biological environmental systems.
