Deep sea carbonates

Deep sea carbonates are calcium carbonate sediments, primarily composed of tiny fossilized shells and coral fragments, that settle on the ocean floor. They form through biological processes when marine organisms like plankton, corals, and mollusks produce calcium carbonate shells. When these organisms die, their shells sink and accumulate on the seabed, creating carbonate-rich deposits. These sediments play a crucial role in the global carbon cycle, as they sequester carbon over millions of years, helping regulate Earth's climate. The study of deep sea carbonates provides insights into past ocean conditions and climate change.
