Minerals By Class
Minerals can be organized, mainly according to their chemistry, into the following classes:
| CLASS | Consisting of: |
| Carbonates | The Carbonates, the Nitrates and the Borates |
| Elements | The Metals and their alloys and the Nonmetals |
| Halides | The Fluorides, the Chlorides and the Iodides |
| Oxides | The Oxides and the Hydroxides |
| Phosphates | The Phosphates, the Arsenates, the Vanadates and the Antimonates |
| Silicates | The Silicates (the largest class) |
| Sulfates | The Sulfates, the Sulfites, the Chromates, the Molybdates, the Selenates, the Selenites, the Tellurates, the Tellurites and the Tungstates (or the Wolframates) |
| Sulfides | The Sulfides, the Selenides, the Tellurides, the Arsenides, the Antimonides, the Bismuthinides and the Sulfosalts |
In addition to the (official) chemistry-based classes, we describe:
| Mineraloids | The "Minerals" that lack crystal structure! |
| Organics | The "Minerals" composed of organic chemicals! |
| Gemstones | The "Mineral Varieties" often described as minerals even though they are only varieties of recognized minerals! |
