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
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

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.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
