Formation of Shale

1 Formation

1.1 Formation

Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

Shale Formation

Shale formation took place millions of years ago. There are a variety of Shale Uses and the Shale 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 Shale is explained below:
