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

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

More about Appinite and Quartzite
Here you can know more about Appinite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Appinite and Quartzite consists of mineral content and compound content. The mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene 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 Appinite vs Quartzite, the texture, color and appearance plays an important role in determining the type of rock. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Appinite is Dull, Banded and Foilated and that of Quartzite is Lustrous. Properties of rock is another aspect for Appinite vs Quartzite. The hardness of Appinite is 5-6 and that of Quartzite is 6-7. The types of Appinite 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 Appinite and Quartzite is white. The specific heat capacity of Appinite is Not Available 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.Appinite is heat resistant, impact resistant whereas Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
