Definition
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism

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.
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.

More about Granulite and Greenschist
Here you can know more about Granulite and Greenschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Greenschist 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 Greenschist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Serpentine, Sillimanite, Staurolite, Talc. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Greenschist, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Greenschist is available in dark greenish - grey, green colors. Appearance of Granulite is Veined or Pebbled and that of Greenschist is Layered and Shiny. Properties of rock is another aspect for Granulite vs Greenschist. The hardness of Granulite is 6-7 and that of Greenschist is 3.5-4. The types of Granulite are Metamorphic rock whereas types of Greenschist are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Greenschist is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Greenschist 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 Greenschist is impact resistant, pressure resistant, water resistant.
