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
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

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.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

All about Cataclasite and Dolomite Properties
Know all about Cataclasite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Cataclasite belongs to Metamorphic Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Cataclasite is Clastic whereas that of Dolomite is Earthy. Cataclasite appears Dull and Banded and Dolomite appears Glassy or Pearly. The luster of Cataclasite is vitreous while that of Dolomite is vitreous and pearly. Cataclasite is available in brown, green, white, yellow colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Cataclasite are commemorative tablets, creating artwork and that of Dolomite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
