Definition

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

A yellow sandstone which is flexible when cut into thin strips

Formation

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.

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