Formation

Formation

Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.
