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.

Epidosite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Granulite and Epidosite

Here you can know more about Granulite and Epidosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Epidosite 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 Epidosite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Epidosite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Epidosite is available in black, brown, light to dark grey colors. Appearance of Granulite is Veined or Pebbled and that of Epidosite is Dull and Soft. Properties of rock is another aspect for Granulite vs Epidosite. The hardness of Granulite is 6-7 and that of Epidosite is 6. The types of Granulite are Metamorphic rock whereas types of Epidosite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. 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 Epidosite is white to grey. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Epidosite 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 Epidosite is heat resistant, pressure resistant, wear resistant.
