Deep-sea Carbonate Deposits

Deep-sea carbonate deposits are layers of calcium carbonate minerals formed on the ocean floor, primarily from the shells and skeletons of marine organisms like corals and plankton. When these organisms die, their remains settle into the deep ocean, accumulating over millions of years to create thick deposits. These deposits play a vital role in the global carbon cycle, helping to store carbon dioxide from the atmosphere. They also provide valuable information about Earth's climate history and are important for understanding ocean chemistry and the planet's geological processes.
