Formation

Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Scoria vs Granulite 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 Granulite Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. 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 Granulite information and Scoria vs Granulite characteristics in the upcoming sections.

Scoria vs Granulite 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 Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Granulite. Learn more about Scoria vs Granulite in the next section. The interior uses of Scoria include Decorative aggregates and Interior decoration whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Scoria and Granulite, 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 Granulite include As dimension stone, Building houses or walls.

More about Scoria and Granulite

Here you can know more about Scoria and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Granulite 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 Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Scoria vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Scoria is Glassy and Vesicular and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Scoria vs Granulite. The hardness of Scoria is 5-6 and that of Granulite is 6-7. The types of Scoria are Basaltic Scoria and Andesitic Scoria whereas types of Granulite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Scoria and Granulite is white. The specific heat capacity of Scoria is 0.84 kJ/Kg K and that of Granulite is 0.14 kJ/Kg K. 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 Granulite is heat resistant, wear resistant.
