Oxide Minerals

Oxide Minerals

The oxide mineral class includes those minerals in which the oxide anion (O2-) is bonded to one or more metal ions. The hydroxide bearing minerals are typically included in the oxide class. The minerals with complex anion groups such as the silicates, sulfates, carbonates and phosphates are classed separately.
