Definition
A yellow sandstone which is flexible when cut into thin strips
Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix

Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
