Formation

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.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Oil shale vs Charnockite 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 Charnockite Reserves. Oil Shale is a fine-grained sedimentary rock from which oil is extracted. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar. 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 Charnockite information and Oil shale vs Charnockite characteristics in the upcoming sections.

Oil shale vs Charnockite Characteristics
