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