Formation
Marl forms when very fine-grained clay particles are deposited in water which settles at the bottom of water bodies and are compacted by overlying sediment; the water squeezes out and hence forming Marl rock.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
