5 Formation
5.1 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.
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
