Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks

Quartzite vs Granite 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 Granite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Granite. Learn more about Quartzite vs Granite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Granite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Quartzite and Granite, 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 Granite include As dimension stone.
More about Quartzite and Granite
Here you can know more about Quartzite and Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Granite 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 Granite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Granite, 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, Granite is available in black, grey, orange, pink, white colors. Appearance of Quartzite is Lustrous and that of Granite is Veined or Pebbled. Properties of rock is another aspect for Quartzite vs Granite. Hardness of Quartzite and Granite is 6-7. The types of Quartzite are Not Available whereas types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite and Granite is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Granite is 0.79 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 Granite is heat resistant, wear resistant.
