Definition

Definition
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase   
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.

Formation

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.   
Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.

Amphibolite vs Kimberlite 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 Amphibolite and Kimberlite Reserves. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.. 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 Amphibolite vs Kimberlite information and Amphibolite vs Kimberlite characteristics in the upcoming sections.

Amphibolite vs Kimberlite 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 Kimberlite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Amphibolite and Properties of Kimberlite. Learn more about Amphibolite vs Kimberlite 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 Kimberlite include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Amphibolite and Kimberlite, 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 Kimberlite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Amphibolite and Kimberlite

Here you can know more about Amphibolite and Kimberlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Amphibolite and Kimberlite 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 Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Amphibolite vs Kimberlite, 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, Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Amphibolite is Foliated and that of Kimberlite is Dull and Banded. Properties of rock is another aspect for Amphibolite vs Kimberlite. Hardness of Amphibolite and Kimberlite is 6-7. The types of Amphibolite are Hornblendite whereas types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites. 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 Kimberlite is white. The specific heat capacity of Amphibolite is Not Available and that of Kimberlite is 0.92 kJ/Kg K. 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 Kimberlite is heat resistant, impact resistant.
