Carbonate Mineral

A Carbonate Mineral is a mineral containing carbonate ions (CO₃^2-) predominantly bonded to metal cations.

• Context:
  • It can commonly be found in Sedimentary Rocks, as they often precipitate from water.
  • It can (often) react with acids, releasing carbon dioxide.
  • It can play a significant role in the Carbon Cycle, helping regulate the Earth's atmosphere and climate.
  • It can be an Economically Important Mineral, as they are a major constituent of limestone.
  • …
• Example(s):
  • Calcite (CaCO₃) - One of the most common carbonate minerals, it is the main constituent of limestone and marble.
  • Dolomite (CaMg(CO₃)₂) - Found in sedimentary rocks and is similar to calcite but contains magnesium.
  • Aragonite (CaCO₃) - A polymorph of calcite, often found in marine environments such as coral reefs.
  • …
• Counter-Example(s):
  • Quartz - A silicate mineral, not containing carbonate ions.
