Quartzite vs Variolite

Quartzite vs Variolite 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 Quartzite and Variolite Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Variolites are a group of dark green basic igneous rocks which exhibit pale colored spots, or spherules, especially on weathered surfaces, that give them a pockmarked appearance. 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 Quartzite vs Variolite information and Quartzite vs Variolite characteristics in the upcoming sections.

Quartzite vs Variolite 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 Variolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Variolite. Learn more about Quartzite vs Variolite in the next section.

Due to some exceptional properties of Quartzite and Variolite, 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 Variolite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.

More about Quartzite and Variolite

Here you can know more about Quartzite and Variolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Variolite 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 Variolite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Variolite, 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, Variolite is available in black, brown, light to dark grey colors. Appearance of Quartzite is Lustrous and that of Variolite is Dull and Soft. Properties of rock is another aspect for Quartzite vs Variolite. The hardness of Quartzite is 6-7 and that of Variolite is 6. The types of Quartzite are Orthoquartzite and Metaquartzite whereas types of Variolite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite is white while that of Variolite is white to grey. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Variolite 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.Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Variolite is heat resistant, pressure resistant, wear resistant.
