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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
