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