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

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.
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.

Cataclasite vs Arkose 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. Cataclasite vs Arkose characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Cataclasite and Properties of Arkose. Learn more about Cataclasite vs Arkose in the next section. The interior uses of Cataclasite include Decorative aggregates and Homes whereas the interior uses of Arkose include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Cataclasite and Arkose, they have various applications in construction industry. The uses of Cataclasite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Arkose include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Cataclasite and Arkose
Here you can know more about Cataclasite and Arkose. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Arkose 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 Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Arkose, 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, Arkose is available in reddish brown colors. Appearance of Cataclasite is Dull and Banded and that of Arkose is Rough and Dull. Properties of rock is another aspect for Cataclasite vs Arkose. The hardness of Cataclasite is 3-4 and that of Arkose is 6-7. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Arkose are Not Available. 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 Arkose is white. The specific heat capacity of Cataclasite is Not Available and that of Arkose is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Cataclasite is heat resistant, impact resistant, pressure resistant whereas Arkose is heat resistant, impact resistant, pressure resistant.
