Carbonate Sediment

Carbonate sediment primarily consists of calcium carbonate, which is formed from the remains of marine organisms like shells and coral. These sediments accumulate on the ocean floor and can create limestone, a common sedimentary rock. Carbonate sediments play a crucial role in the carbon cycle, influencing climate and ocean chemistry. They also serve as important indicators of past environmental conditions and are vital for marine ecosystems, providing habitats for a variety of marine life. In summary, carbonate sediments are key components of Earth's geological and ecological systems.
