Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

Quartzite vs Jasperoid 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 Jasperoid characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Jasperoid. Learn more about Quartzite vs Jasperoid in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Jasperoid include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Quartzite and Jasperoid, 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 Jasperoid 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, Production of glass and ceramics, Serves as an oil and gas reservoir rock.
More about Quartzite and Jasperoid
Here you can know more about Quartzite and Jasperoid. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Jasperoid 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 Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Jasperoid, 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, Jasperoid is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Quartzite is Lustrous and that of Jasperoid is Glassy or Pearly. Properties of rock is another aspect for Quartzite vs Jasperoid. The hardness of Quartzite is 6-7 and that of Jasperoid is 3.5-4. The types of Quartzite are Not Available whereas types of Jasperoid 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 Jasperoid is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Jasperoid 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 Jasperoid is heat resistant, pressure resistant, wear resistant.
