Boninite vs Scoria 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 Boninite and Scoria Reserves. Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. 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 Boninite vs Scoria information and Boninite vs Scoria characteristics in the upcoming sections.

Boninite vs Scoria 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. Boninite vs Scoria characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Boninite and Properties of Scoria. Learn more about Boninite vs Scoria in the next section. The interior uses of Boninite include Decorative aggregates, Homes and Kitchens whereas the interior uses of Scoria include Decorative aggregates and Interior decoration. Due to some exceptional properties of Boninite and Scoria, they have various applications in construction industry. The uses of Boninite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Scoria include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works.

More about Boninite and Scoria

Here you can know more about Boninite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Scoria consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Scoria, the texture, color and appearance plays an important role in determining the type of rock. Boninite is available in bluish - grey, brown, green, grey colors whereas, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Boninite is Dull and Soft and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Boninite vs Scoria. The hardness of Boninite is 7 and that of Scoria is 5-6. The types of Boninite are Basalt whereas types of Scoria are Basaltic Scoria and Andesitic Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Boninite and Scoria is white. The specific heat capacity of Boninite is 0.84 kJ/Kg K and that of Scoria is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Boninite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
