Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Quartzite vs Granulite 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 Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Granulite. Learn more about Quartzite vs Granulite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Quartzite and Granulite, 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 Granulite include As dimension stone, Building houses or walls.
More about Quartzite and Granulite
Here you can know more about Quartzite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Granulite 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 Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Quartzite is Lustrous and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Quartzite vs Granulite. Hardness of Quartzite and Granulite is 6-7. The types of Quartzite are Not Available whereas types of Granulite 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 Granulite is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
