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.

Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
