Mineral Gallery the Phosphates Class

The Phosphate Class is made up of minerals with a basic chemical unit of tetrahedral (AO4) groups with a negative three (3) charge.The A can be either Phosphorus, Arsenic, Vanadium or Antimony. The basic chemical unit can be combined with metal ions on a one to one ratio or usually in more complex combinations with other ions such as hydroxide groups (OH), uranyl groups (UO2), a halogen or
