Limestone formula

Limestone is a common type of rock in geology. It has a rich history in geological research and a wide array of uses that extend from construction to agriculture. Let’s dive deeper.

What is Limestone?

Limestone is a type of carbonate sedimentary rock primarily composed of calcium carbonate (CaCO3).

Where is limestone found

It typically comprises two different minerals: calcite and aragonite, which have the same chemical formula but different types of crystals.

Limestone forms through both chemical and biological processes, including the accumulation of sea creatures‘ shells and corals.

In fact, these rocks often come from organic sources.

The Formation and Composition of Limestone

Limestone’s journey from a simple sediment to a sedimentary rock is a fascinating story of Earth’s geological processes.

This process, taking place over millions of years, usually involves a combination of biological, chemical, and physical factors.

Biological Formation

Many marine organisms, such as corals, foraminifera, and mollusks have shells or structures made of calcium carbonate.
