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.
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

Amphibolite vs Arkose 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 Arkose Reserves. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar. 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 Arkose information and Amphibolite vs Arkose characteristics in the upcoming sections.

Amphibolite vs Arkose 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 Arkose characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Amphibolite and Properties of Arkose. Learn more about Amphibolite vs Arkose 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 Arkose include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Amphibolite and Arkose, 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 Arkose include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.

More about Amphibolite and Arkose

Here you can know more about Amphibolite and Arkose. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Amphibolite and Arkose 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 Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Amphibolite vs Arkose, 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, Arkose is available in reddish brown colors. Appearance of Amphibolite is Foliated and that of Arkose is Rough and Dull. Properties of rock is another aspect for Amphibolite vs Arkose. Hardness of Amphibolite and Arkose is 6-7. The types of Amphibolite are Hornblendite whereas types of Arkose 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 Arkose is white. The specific heat capacity of Amphibolite is Not Available and that of Arkose 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 Arkose is heat resistant, impact resistant, pressure resistant.
