Formation

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

More about Granulite and Appinite

Here you can know more about Granulite and Appinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Appinite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, 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 Granulite vs Appinite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Granulite is Veined or Pebbled and that of Appinite is Dull, Banded and Foilated. Properties of rock is another aspect for Granulite vs Appinite. The hardness of Granulite is 6-7 and that of Appinite is 5-6. The types of Granulite are Metamorphic rock whereas types of Appinite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Appinite is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Appinite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Appinite is heat resistant, impact resistant.
