22113 - Lustrous Yellow Green Apatite Crystals on Brecciated Matrix - Imilchil (Morocco) Spinosaurus Claws kamacite Ni=7Apatite is a group of phosphate minerals, usually referring to hydroxylapatite, fluorapatite and chlorapatite, with high concentrations of OH, F and Cl ions, respectively, in the crystal. The formula of the admixture of the three most common endmembers is written as Ca10(PO4)6(OH,F,Cl)2.
