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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
