6 · Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO3) in the form of the mineral calcite. It often forms in clear, warm, shallow marine waters through two main processes: the accumulation of carbonate mud and the deposition of shells, coral, algae, and fecal debris. Limestone can also form through evaporative
