Oil shale Formation

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