1.1 Definition

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

A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

5 Formation

5.1 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.

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Amphibolite vs Serpentinite 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 Serpentinite Reserves. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.. 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 Serpentinite information and Amphibolite vs Serpentinite characteristics in the upcoming sections.

Amphibolite vs Serpentinite 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 Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Amphibolite and Properties of Serpentinite. Learn more about Amphibolite vs Serpentinite 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 Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Amphibolite and Serpentinite, 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 Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.

More about Amphibolite and Serpentinite

Here you can know more about Amphibolite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Amphibolite and Serpentinite 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 Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Amphibolite vs Serpentinite, 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, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Amphibolite is Foliated and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Amphibolite vs Serpentinite. The hardness of Amphibolite is 6-7 and that of Serpentinite is 3-5. The types of Amphibolite are Hornblendite whereas types of Serpentinite are Jadeitite. 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 Serpentinite is white, greenish white or grey. The specific heat capacity of Amphibolite is Not Available and that of Serpentinite is 0.95 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 Serpentinite is heat resistant.
