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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

More about Granulite and Andesite
Here you can know more about Granulite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Andesite 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 Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Andesite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Granulite is Veined or Pebbled and that of Andesite is Dull and Soft. Properties of rock is another aspect for Granulite vs Andesite. The hardness of Granulite is 6-7 and that of Andesite is 7. The types of Granulite are Metamorphic rock whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Andesite is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Andesite is 2.39 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 Andesite is heat resistant, pressure resistant, wear resistant.
