Formation

Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.

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