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