Formation

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 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.

Serpentinite 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 Serpentinite and Amphibolite Reserves. 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'.. 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 Serpentinite vs Amphibolite information and Serpentinite vs Amphibolite characteristics in the upcoming sections.

Serpentinite 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. Serpentinite vs Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Amphibolite. Learn more about Serpentinite vs Amphibolite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Serpentinite and Amphibolite, they have various applications in construction industry. The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement 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 Serpentinite and Amphibolite

Here you can know more about Serpentinite and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Amphibolite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides 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 Serpentinite vs Amphibolite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Amphibolite is available in black, brown, green, grey colors. Appearance of Serpentinite is Rough and Dull and that of Amphibolite is Foliated. Properties of rock is another aspect for Serpentinite vs Amphibolite. The hardness of Serpentinite is 3-5 and that of Amphibolite is 6-7. The types of Serpentinite are Jadeitite 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 Serpentinite is white, greenish white or grey while that of Amphibolite is white to grey. The specific heat capacity of Serpentinite is 0.95 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.Serpentinite is heat resistant whereas Amphibolite is heat resistant, pressure resistant, wear resistant.
