biogenic limestone

Biogenic limestone is a type of rock formed primarily from the accumulation of biological materials, such as shells, coral, and other remains of marine organisms. Over millions of years, these materials can cement together, resulting in a solid rock. Biogenic limestone often forms in shallow ocean environments where sunlight supports the growth of organisms like corals and mollusks. This rock is significant in geology and paleontology as it provides insights into past marine ecosystems and can be a valuable resource for construction and industry, particularly in making cement.
