for us a versatile source of raw materials for modern life
For others, it's just a rock

Calcium carbonate (CaCO3) is among the most plentiful minerals on Earth, comprising approximately 4% of the planet's crust. Naturally, it is found in three primary rock forms: chalk, limestone, and marble.

Where does calcium carbonate come from? Most calcium carbonate deposits were formed by dead marine organisms such as crustaceans, algae and corals. During their lives, these organisms absorbed calcium carbonate from the water and used it to build up their shells and skeletons. 
After their death, their remains were deposited as sediment on the sea floor. Over the course of millions of years, nature used them to build the rocks that we use today.
Limestone is the compacted and hardened form of sedimentary rock.

Chalk is a soft rock. It is the result of a poorly compacted sedimentary calcium carbonate rock whose diagenesis is incomplete. 

Marble is the hardest form of calcium carbonate. It is formed by recrystallization of limestone under high pressure and temperature conditions.

Limestone is one of the most versatile natural resources. Limestone often goes unnoticed, even though it plays a crucial role in many applications in our daily lives. Whether in paper, plastics, concrete and asphalt, paints and varnishes, pharmaceuticals or agriculture, limestone is used almost everywhere. Its versatility makes it one of the most widely used resources. Special qualities and high-quality processing also make it a valuable source of raw materials.

The color is an important quality feature. Pure calcium carbonate is white. However, limestone can also be beige or gray due to contamination with clay, sand, iron, organic material, etc.
