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

Formation
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.
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 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. Amphibolite vs Cataclasite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Amphibolite and Properties of Cataclasite. Learn more about Amphibolite vs Cataclasite in the next section. The interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens whereas the interior uses of Cataclasite include Decorative aggregates and Homes. Due to some exceptional properties of Amphibolite and Cataclasite, they have various applications in construction industry. The uses of Amphibolite in construction industry include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone and that of Cataclasite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Amphibolite and Cataclasite
Here you can know more about Amphibolite and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Amphibolite and Cataclasite consists of mineral content and compound content. The mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite 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 . When we have to compare Amphibolite vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Amphibolite is available in black, brown, green, grey colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Amphibolite is Foliated and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Amphibolite vs Cataclasite. The hardness of Amphibolite is 6-7 and that of Cataclasite is 3-4. The types of Amphibolite are Hornblendite 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 Amphibolite is white to grey while that of Cataclasite is black. The specific heat capacity of Amphibolite 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.Amphibolite is heat resistant, pressure resistant, wear resistant whereas Cataclasite is heat resistant, impact resistant, pressure resistant.
