Sulfate, Halide and Phosphate Minerals: What do they look like? Why are they important? |
| Minerals belonging to the sulfate, halide and phosphate groups are all commonly classified as non-silicate minerals. Sulfates are defined as minerals whose chemical composition consist of both sulfur and oxygen, with sulfur acting as the cation. Halides are defined as minerals whose primary anion comes from the halogen group (i.e. chlorine, fluorine, iodine, etc.). Phosphates contain the (PO4)3- anion.
