Mineral Class 07: Phosphates, Arsenates, Vanadates | |
Phosphate minerals are those minerals that contain the tetrahedrally coordinated phosphate (PO4) anion along with the freely substituting arsenate (AsO43-) and vanadate (VO43-). Chlorine (Cl-), fluorine (F-), and hydroxide (OH-) anions also fit into the crystal structure. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common.
