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