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.

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Granulite and Metapelite

Here you can know more about Granulite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Metapelite 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 Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Granulite is Veined or Pebbled and that of Metapelite is Banded. Properties of rock is another aspect for Granulite vs Metapelite. The hardness of Granulite is 6-7 and that of Metapelite is 5-6. The types of Granulite are Metamorphic rock whereas types of Metapelite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite is white while that of Metapelite is . The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Metapelite is 0.72 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 Metapelite is heat resistant, impact resistant, pressure resistant.
