Formation

Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.   
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.

Scoria 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 Scoria and Amphibolite Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. 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 Scoria vs Amphibolite information and Scoria vs Amphibolite characteristics in the upcoming sections.

Scoria 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. Scoria vs Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Amphibolite. Learn more about Scoria vs Amphibolite in the next section. The interior uses of Scoria 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 Scoria and Amphibolite, they have various applications in construction industry. The uses of Scoria in construction industry include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works 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 Scoria and Amphibolite

Here you can know more about Scoria and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Amphibolite consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica 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 Igneous Rocks. When we have to compare Scoria vs Amphibolite, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Amphibolite is available in black, brown, green, grey colors. Appearance of Scoria is Glassy and Vesicular and that of Amphibolite is Foliated. Properties of rock is another aspect for Scoria vs Amphibolite. The hardness of Scoria is 5-6 and that of Amphibolite is 6-7. The types of Scoria are Not Available 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 Scoria is white while that of Amphibolite is white to grey. The specific heat capacity of Scoria 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.Scoria is heat resistant, impact resistant, pressure resistant, wear resistant whereas Amphibolite is heat resistant, pressure resistant, wear resistant.
