Definition

Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar

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

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

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.
