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.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
