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.

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
