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

Chert and Jasper
Features
Easily splits into thin plates, Is one of the oldest rock
Clasts are smooth to touch, Easily splits into thin plates, Has High structural resistance against erosion and climate
Archaeological Significance
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.

More about Cataclasite and Flint
Here you can know more about Cataclasite and Flint. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Flint consists of mineral content and compound content. The mineral content of Cataclasite includes Albite, Apatite, Augite, Biotite, Calcite, Enstatite, Epidote, Feldspar, Micas, Muscovite or Illite, Pyroxene, Quartz and mineral content of Flint includes Silicon. You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Flint, the texture, color and appearance plays an important role in determining the type of rock. Cataclasite is available in brown, green, white, yellow colors whereas, Flint is available in black, brown, green, grey, red, white colors. Appearance of Cataclasite is Dull and Banded and that of Flint is Glassy or Pearly. Properties of rock is another aspect for Cataclasite vs Flint. The hardness of Cataclasite is 3-4 and that of Flint is 7. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Flint are Chert and Jasper. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Cataclasite is black while that of Flint is white.
