Formation

Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

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