Quartzite vs Itacolumite 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. Quartzite vs Itacolumite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Itacolumite. Learn more about Quartzite vs Itacolumite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Itacolumite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Quartzite and Itacolumite, they have various applications in construction industry. The uses of Quartzite in construction industry 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 and that of Itacolumite include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Quartzite and Itacolumite
Here you can know more about Quartzite and Itacolumite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Itacolumite consists of mineral content and compound content. The mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz and mineral content of Itacolumite includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Itacolumite, the texture, color and appearance plays an important role in determining the type of rock. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas, Itacolumite is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Quartzite is Lustrous and that of Itacolumite is Rough. Properties of rock is another aspect for Quartzite vs Itacolumite. Hardness of Quartzite and Itacolumite is 6-7. The types of Quartzite are Not Available whereas types of Itacolumite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite and Itacolumite is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Itacolumite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Itacolumite is heat resistant, impact resistant, pressure resistant.
