Class of minerals containing oxygen
Oxide mineral exhibit at the Museum of Geology in South Dakota The oxide mineral class includes those minerals in which the oxide anion (O2− ) is bonded to one or more metal alloys. The hydroxide -bearing minerals are typically included in the oxide class. Minerals with complex anion groups such as the silicates , sulfates , carbonates and phosphates are classed separately.
Nickel–Strunz class 4: oxides
IMA -CNMNC proposes a new hierarchical scheme (Mills et al., 2009). This list uses it to modify the Nickel–Strunz classification (mindat.org , 10 ed, pending publication).
