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.
Pantellerite 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 Pantellerite
Here you can know more about Granulite and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Pantellerite 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 Pantellerite includes Amphibole, Feldspar, Ilmenite. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Granulite is Veined or Pebbled and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Granulite vs Pantellerite. Hardness of Granulite and Pantellerite is 6-7. The types of Granulite are Not Available whereas types of Pantellerite are Pantelleritic Ignimbrite. 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 Pantellerite is unknown. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Pantellerite is Not Available. 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 Pantellerite is heat resistant.
