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

Granodiorite 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. Granodiorite vs Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granodiorite and Properties of Quartzite. Learn more about Granodiorite vs Quartzite in the next section. The interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Granodiorite and Quartzite, they have various applications in construction industry. The uses of Granodiorite in construction industry include As dimension stone 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 Granodiorite and Quartzite
Here you can know more about Granodiorite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Quartzite consists of mineral content and compound content. The mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, 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 Igneous Rocks. When we have to compare Granodiorite vs Quartzite, the texture, color and appearance plays an important role in determining the type of rock. Granodiorite is available in black, grey, orange, pink, white colors whereas, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Granodiorite is Veined or Pebbled and that of Quartzite is Lustrous. Properties of rock is another aspect for Granodiorite vs Quartzite. The hardness of Granodiorite is 6 and that of Quartzite is 6-7. The types of Granodiorite are Not Available whereas types of Quartzite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granodiorite and Quartzite is white. The specific heat capacity of Granodiorite is 0.79 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.Granodiorite is heat resistant, wear resistant whereas Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
