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.
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.

Amphibolite vs Greenschist 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 Greenschist Reserves. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism. 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 Greenschist information and Amphibolite vs Greenschist characteristics in the upcoming sections.

Amphibolite vs Greenschist 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 Greenschist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Amphibolite and Properties of Greenschist. Learn more about Amphibolite vs Greenschist 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 Greenschist include Bathrooms, Countertops, Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Amphibolite and Greenschist, 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 Greenschist include As dimension stone, Building houses or walls, Cement manufacture, Cutting tool, For road aggregate, Roadstone.

More about Amphibolite and Greenschist

Here you can know more about Amphibolite and Greenschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Amphibolite and Greenschist 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 Greenschist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Serpentine, Sillimanite, Staurolite, Talc. You can also check out the list of all Igneous Rocks. When we have to compare Amphibolite vs Greenschist, 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, Greenschist is available in dark greenish - grey, green colors. Appearance of Amphibolite is Foliated and that of Greenschist is Layered and Shiny. Properties of rock is another aspect for Amphibolite vs Greenschist. The hardness of Amphibolite is 6-7 and that of Greenschist is 3.5-4. The types of Amphibolite are Hornblendite whereas types of Greenschist are Not Available. 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 Greenschist is white. The specific heat capacity of Amphibolite is Not Available and that of Greenschist 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 Greenschist is impact resistant, pressure resistant, water resistant.
