Definition
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar
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

Etymology
From Auvergne region of France used by a French geologist Alexandre Brongniart in 1826 who applied this term to some feldspathic sandstones
From the Italian word cataclasi

Formation
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.
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.

Arkose 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. Arkose vs Cataclasite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Arkose and Properties of Cataclasite. Learn more about Arkose vs Cataclasite in the next section. The interior uses of Arkose include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Cataclasite include Decorative aggregates and Homes. Due to some exceptional properties of Arkose and Cataclasite, they have various applications in construction industry. The uses of Arkose in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar and that of Cataclasite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Arkose and Cataclasite
Here you can know more about Arkose and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Arkose and Cataclasite consists of mineral content and compound content. The mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz 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 Arkose vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Arkose is available in reddish brown colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Arkose is Rough and Dull and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Arkose vs Cataclasite. The hardness of Arkose is 6-7 and that of Cataclasite is 3-4. The types of Arkose are Not Available 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 Arkose is white while that of Cataclasite is black. The specific heat capacity of Arkose is Not Available 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.Arkose is heat resistant, impact resistant, pressure resistant whereas Cataclasite is heat resistant, impact resistant, pressure resistant.
