Apatite is a group of phosphate minerals with a general formula of Ca5(PO4)3(X), where X can represent various anions, including OH (hydroxyl), F (fluorine), and Cl (chlorine). The variable composition of apatite is due to the substitution of these different anions in its crystal structure. The basic structure of apatite is a hexagonal crystal lattice that allows for the incorporation of different ions and anions in the crystal structure, leading to various types of apatite with slightly different properties.
