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
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.
Origin
Swiss Alps, Europe
Kimberley, South Africa
Discoverer

Etymology
From the Italian word cataclasi
From Kimberley + -ite, from the name of the South African town of Kimberley where the rock was first found.

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.
Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.

More about Cataclasite and Kimberlite
Here you can know more about Cataclasite and Kimberlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Kimberlite 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 Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Kimberlite, 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, Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Cataclasite is Dull and Banded and that of Kimberlite is Dull and Banded. Properties of rock is another aspect for Cataclasite vs Kimberlite. The hardness of Cataclasite is 3-4 and that of Kimberlite is 6-7. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites.
