How Limestone is Formed: A Journey Through Geological Time
Limestone, a sedimentary rock predominantly composed of calcium carbonate (CaCO₃), is a significant geological resource that tells the story of Earth's history.
The formation of limestone is a complex process that spans millions of years, involving the interplay of biological, chemical, and physical factors. Understanding how limestone is formed requires a journey through geological time, exploring the intricate processes that contribute to its creation.
The Origin of Limestone: A Marine Tale
Limestone formation is closely linked to the marine environment.
What type of rock is limestoneThe primary source of calcium carbonate in limestone is marine organisms such as corals, foraminifera, and mollusks. These organisms use calcium and carbonate ions from seawater to build their shells and skeletons. When these organisms die, their remains settle on the ocean floor, forming a thick layer of calcium carbonate-rich sediment.
Over time, this sediment undergoes compaction and cementation, transforming into limestone.
