Definition
Oil Shale is a fine-grained sedimentary rock from which oil is extracted
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
