carbonates (group of minerals)

Carbonates are a group of minerals that contain the carbonate ion (CO₃²⁻). They often form in sedimentary environments and play an essential role in the Earth's geology. Common examples include calcite, found in limestone and marble, and dolomite. Carbonates are important for several reasons: they contribute to soil health, act as carbon sinks, and have various industrial uses, such as in cement production. Additionally, they are significant in the formation of rocks and can help us understand past environmental conditions.
