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
Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle

Archaeological Significance
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.
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

Cataclasite vs Peridotite 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 Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Cataclasite and Properties of Peridotite. Learn more about Cataclasite vs Peridotite in the next section. The interior uses of Cataclasite include Decorative aggregates and Homes whereas the interior uses of Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Cataclasite and Peridotite, 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 Peridotite include As dimension stone, Cobblestones.
More about Cataclasite and Peridotite
Here you can know more about Cataclasite and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Peridotite 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 Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Peridotite, 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, Peridotite is available in dark greenish - grey colors. Appearance of Cataclasite is Dull and Banded and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Cataclasite vs Peridotite. The hardness of Cataclasite is 3-4 and that of Peridotite is 5.5-6. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. 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 Peridotite is white. The specific heat capacity of Cataclasite is 0.84 kJ/Kg K and that of Peridotite is 1.26 kJ/Kg K. 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 Peridotite is heat resistant, pressure resistant, wear resistant.
