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.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

More about Granulite and Diorite
Here you can know more about Granulite and Diorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Diorite 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 Diorite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Diorite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Diorite is available in black, brown, light to dark grey, white colors. Appearance of Granulite is Veined or Pebbled and that of Diorite is Shiny. Properties of rock is another aspect for Granulite vs Diorite. Hardness of Granulite and Diorite is 6-7. The types of Granulite are Not Available whereas types of Diorite are Not Available. 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 Diorite is bluish black. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Diorite 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 Diorite is heat resistant, pressure resistant, wear resistant.
