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.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
