Gneiss vs Amphibolite

Gneiss 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 Gneiss and Amphibolite Reserves. Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. 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 Gneiss vs Amphibolite information and Gneiss vs Amphibolite characteristics in the upcoming sections.

Gneiss 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. Gneiss vs Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gneiss and Properties of Amphibolite. Learn more about Gneiss vs Amphibolite in the next section. The interior uses of Gneiss include Countertops, Decorative aggregates, Flooring 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 Gneiss and Amphibolite, they have various applications in construction industry. The uses of Gneiss in construction industry include As dimension stone 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 Gneiss and Amphibolite

Here you can know more about Gneiss and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gneiss and Amphibolite consists of mineral content and compound content. The mineral content of Gneiss includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon 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 Gneiss vs Amphibolite, the texture, color and appearance plays an important role in determining the type of rock. Gneiss is available in black, brown, pink, red, white colors whereas, Amphibolite is available in black, brown, green, grey colors. Appearance of Gneiss is Foliated and that of Amphibolite is Foliated. Properties of rock is another aspect for Gneiss vs Amphibolite. The hardness of Gneiss is 7 and that of Amphibolite is 6-7. The types of Gneiss are Augen Gneiss, Henderson Gneiss, Lewisian Gneiss, Archean and Proterozoic Gneiss. 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 Gneiss is white while that of Amphibolite is white to grey. The specific heat capacity of Gneiss is Not Available and that of Amphibolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Gneiss is heat resistant, pressure resistant, scratch resistant, wear resistant whereas Amphibolite is heat resistant, pressure resistant, wear resistant.
