5 Formation
5.1 Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
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.
