Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
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.
