Definition
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

Archaeological Significance
Formation
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 forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Granulite 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. Granulite vs Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Quartzite. Learn more about Granulite vs Quartzite in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Granulite and Quartzite, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls 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 Granulite and Quartzite
Here you can know more about Granulite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Quartzite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Quartzite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Granulite is Veined or Pebbled and that of Quartzite is Lustrous. Properties of rock is another aspect for Granulite vs Quartzite. Hardness of Granulite and Quartzite is 6-7. The types of Granulite are Metamorphic rock whereas types of Quartzite are Orthoquartzite and Metaquartzite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Quartzite is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K 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.Granulite is heat resistant, wear resistant whereas Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
