Carbonate minerals are those minerals containing the carbonate ion: CO32-.

Carbonate divisions[edit]

Anhydrous carbonates[edit]

Rhodochrosite, Sweet Home Mine, Alma, Colorado - 5.2 × 4.2 × 2.3 cm
Smithsonite, Silver Bill Mine, Dragoon Mts, Cochise County, Arizona - 4.8 × 4.1 × 2.4 cm

Anhydrous carbonates with compound formulas[edit]

Dolomite with calcite and chalcopyrite from the Picher Field, Tri-State district, Cherokee County, Kansas; 12.0 × 9.7 × 4.3 cm

Carbonates with hydroxyl or halogen[edit]

Azurite and malachite, Beaver Dam Mts, Washington County, Utah - 5.1 × 3.9 × 2.4 cm

Hydrated carbonates[edit]

The carbonate class in both the Dana and the Strunz classification systems include the nitrates.[1][2]

Nickel–Strunz Classification -05- Carbonates[edit]

Hanksite, Na22K(SO4)9(CO3)2Cl, one of the few minerals that is considered a carbonate and a sulfate

IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009).[3] This list uses the Classification of Nickel–Strunz (mindat.org, 10 ed, pending publication).[2]
