Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
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 vs Granodiorite 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 Granodiorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Granodiorite. Learn more about Quartzite vs Granodiorite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads. Due to some exceptional properties of Quartzite and Granodiorite, 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 Granodiorite include As dimension stone.
More about Quartzite and Granodiorite
Here you can know more about Quartzite and Granodiorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Granodiorite 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 Granodiorite 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 Granodiorite, 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, Granodiorite is available in black, grey, orange, pink, white colors. Appearance of Quartzite is Lustrous and that of Granodiorite is Veined or Pebbled. Properties of rock is another aspect for Quartzite vs Granodiorite. The hardness of Quartzite is 6-7 and that of Granodiorite is 6. The types of Quartzite are Not Available whereas types of Granodiorite 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 Granodiorite is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Granodiorite 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 Granodiorite is heat resistant, wear resistant.
