Scoria vs Quartzite 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 Quartzite Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. 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 Quartzite information and Scoria vs Quartzite characteristics in the upcoming sections.

Scoria vs Quartzite 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 Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Quartzite. Learn more about Scoria vs Quartzite in the next section. The interior uses of Scoria include Decorative aggregates and Interior decoration whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Scoria and Quartzite, 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 Quartzite include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone.

More about Scoria and Quartzite

Here you can know more about Scoria and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Quartzite 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 Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Scoria vs Quartzite, 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, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Scoria is Glassy and Vesicular and that of Quartzite is Lustrous. Properties of rock is another aspect for Scoria vs Quartzite. The hardness of Scoria is 5-6 and that of Quartzite is 6-7. The types of Scoria are Not Available whereas types of Quartzite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Scoria and Quartzite is white. The specific heat capacity of Scoria is Not Available and that of Quartzite is 0.75 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 Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
