Chalk Formation

Chalk formation took place millions of years ago. There are a variety of Chalk Uses and the Chalk Reserves are found in many countries around the world. The rocks in the earth’s crust continuously undergo changes in their composition which leads to formation of other rocks. Each rock has a unique formation process. Formation of Chalk is explained below:

  • Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
