Phosphate minerals are minerals that contain the tetrahedrally coordinated phosphate (PO 43−) anion, sometimes with arsenate (AsO 43−) and vanadate (VO 43−) substitutions, along with chloride (Cl − ), fluoride (F − ), and hydroxide (OH −) anions, that also fit into the crystal structure . The phosphate class of minerals is a large
