carboniferous limestone

Carboniferous limestone is a type of sedimentary rock formed around 300 million years ago during the Carboniferous period. It develops from the accumulation of calcium carbonate, mainly from the remains of marine organisms like corals and shells, in warm, shallow seas. Over time, these sediments compact and cement together, creating a durable limestone. This rock is typically light-colored, porous, and often contains fossils. It is important both geologically and historically, serving as a key material in construction and contributing to the formation of important fossil fuels like coal, which developed in related environments.
