Group of minerals that contain one or more metallic elements plus the carbonate radical (CO3). Most are lightly colored and transparent when pure. All carbonates are soft, brittle, and effervesce when exposed to warm hydrochloric acid. The carbonates are divided into Calcite Group and Aragonite Group. The Nitrates and Borates are sometimes considered a category of the carbonates.
Rocks such as limestone and dolomite that are comprised principally of carbonate minerals.
Minerals (such as calcite) that contain carbon.
A group of minerals, all containing the carbonate radical (CO3), common in veins and in altered rocks.
(car´-bon-ate) A mineral compound characterized by a fundamental anionic structure of CO3–2. Calcite and aragonite CaCO3, are examples of carbonates. A sediment formed of the carbonates of calcium, magnesium, and /or iron, e.g. limestone and dolomite.
Alkaline salts whose anions are derived from carbonic acid.
sedimentary rocks composed of calcium and/or magnesium carbonate e.g. limestone.
