The term "carbonates" generally refers to a class of chemical compounds that contain the carbonate ion (CO₃²⁻). However, if you are looking for a sample name or specific examples of carbonate minerals, some common examples include:
- Calcite (CaCO₃) - A common carbonate mineral and the primary component of limestone.
- Dolomite (CaMg(CO₃)₂) - A mineral that is often found in sedimentary rock formations.
- Aragonite (CaCO₃) - Another form of calcium carbonate, typically found in marine environments.
- Siderite (FeCO₃) - An iron carbonate mineral.
- Rhodochrosite (MnCO₃) - A manganese carbonate mineral.
