Cataclasite vs Amphibolite

Definition

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
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase

Formation

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.
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

Cataclasite vs Amphibolite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Cataclasite and Amphibolite Reserves. 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. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Cataclasite vs Amphibolite information and Cataclasite vs Amphibolite characteristics in the upcoming sections.

Cataclasite vs Amphibolite 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 Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Cataclasite and Properties of Amphibolite. Learn more about Cataclasite vs Amphibolite in the next section. The interior uses of Cataclasite include Decorative aggregates and Homes whereas the interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Cataclasite and Amphibolite, 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 Amphibolite include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone.

More about Cataclasite and Amphibolite

Here you can know more about Cataclasite and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Amphibolite 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 Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite. You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Amphibolite, 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, Amphibolite is available in black, brown, green, grey colors. Appearance of Cataclasite is Dull and Banded and that of Amphibolite is Foliated. Properties of rock is another aspect for Cataclasite vs Amphibolite. The hardness of Cataclasite is 3-4 and that of Amphibolite is 6-7. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Amphibolite are Hornblendite. 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 Amphibolite is white to grey. The specific heat capacity of Cataclasite is 0.84 kJ/Kg K and that of Amphibolite is 0.84 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 Amphibolite is heat resistant, pressure resistant, wear resistant.
