Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

Quartzite vs Appinite 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 Appinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Appinite. Learn more about Quartzite vs Appinite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Appinite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Quartzite and Appinite, 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 Appinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Quartzite and Appinite
Here you can know more about Quartzite and Appinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Appinite 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 Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Appinite, 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, Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Quartzite is Lustrous and that of Appinite is Dull, Banded and Foilated. Properties of rock is another aspect for Quartzite vs Appinite. The hardness of Quartzite is 6-7 and that of Appinite is 5-6. The types of Quartzite are Not Available whereas types of Appinite 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 Appinite is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Appinite is Not Available. 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 Appinite is heat resistant, impact resistant.
