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.

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
