Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
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
Origin
Southern Alps, France

Etymology
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock
From the Italian word cataclasi

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
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 vs Cataclasite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Dolomite vs Cataclasite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Cataclasite. Learn more about Dolomite vs Cataclasite in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Cataclasite include Decorative aggregates and Homes. Due to some exceptional properties of Dolomite and Cataclasite, they have various applications in construction industry. The uses of Dolomite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock and that of Cataclasite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Dolomite and Cataclasite
Here you can know more about Dolomite and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Cataclasite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Cataclasite includes Albite, Apatite, Augite, Biotite, Calcite, Enstatite, Epidote, Feldspar, Micas, Muscovite or Illite, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Dolomite is Glassy or Pearly and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Dolomite vs Cataclasite. The hardness of Dolomite is 3.5-4 and that of Cataclasite is 3-4. The types of Dolomite are Boninite and Jasperoid whereas types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite is white while that of Cataclasite is black. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Cataclasite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dolomite is heat resistant, pressure resistant, wear resistant whereas Cataclasite is heat resistant, impact resistant, pressure resistant.
