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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
