| - Carbonate rocks are rocks made up primarily of carbonate minerals (minerals containing the CO3 anionic structure). The two most common carbonate minerals are Calcite - , and Dolomite - . Generally, carbonates are associated only with sedimentary rocks, but there have been extremely rare volcanic carbonate eruptions, namely in Mt. Vulture, southern Italy (Abstract), and in Africa.
- In chemistry, a carbonate is a salt of carbonic acid, characterized by the presence of the carbonate ion, CO3 2-. The name may also mean an ester of carbonic acid, an organic compound containing the carbonate group C(=O)(O–)2. The term is also used as a verb, to describe carbonation: the process of raising the concentrations of carbonate and bicarbonate ions in water to produce carbonated water and other carbonated beverages — either by the addition of carbon dioxide gas under pressure, or by dissolving carbonate or bicarbonate salts into the water.

The name may also mean an ester of carbonic acid, an organic compound containing the carbonate group C(=O)(O–)2.

In geology and mineralogy, the term "carbonate" can refer both to carbonate minerals and carbonate rock (which is made of chiefly carbonate minerals), and both are dominated by the carbonate ion, CO. Carbonate minerals are extremely varied and ubiquitous in chemically precipitated sedimentary rock. The most common are calcite or calcium carbonate, CaCO3, the chief constituent of limestone (as well as the main component of mollusc shells and coral skeletons); dolomite, a calcium-magnesium carbonate CaMg(CO3)2; and siderite, or iron(II) carbonate, FeCO3, an important iron ore. Sodium carbonate ("soda" or "natron") and potassium carbonate ("potash") have been used since antiquity for cleaning and preservation, as well as for the manufacture of glass. Carbonates are widely used in industry, e.g. in iron smelting, as a raw material for Portland cement and lime manufacture, in the composition of ceramic glazes, and more.
