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; B is phosphorus, vanadium, or arsenic; and X is chlorine, fluorine, or hydroxyl. The group contains three series: the apatite, the pyromorphite, and the svabite (intermediate between the other two).
