5 Formation

5.1 Formation

Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

Oil shale vs Dunite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Oil shale and Dunite Reserves. Oil Shale is a fine-grained sedimentary rock from which oil is extracted. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Oil shale vs Dunite information and Oil shale vs Dunite characteristics in the upcoming sections.
