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.
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

Granulite vs Granodiorite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Granulite vs Granodiorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Granodiorite. Learn more about Granulite vs Granodiorite in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads. Due to some exceptional properties of Granulite and Granodiorite, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls and that of Granodiorite include As dimension stone.
More about Granulite and Granodiorite
Here you can know more about Granulite and Granodiorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Granodiorite 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 Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Granodiorite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Granodiorite is available in black, grey, orange, pink, white colors. Appearance of Granulite is Veined or Pebbled and that of Granodiorite is Veined or Pebbled. Properties of rock is another aspect for Granulite vs Granodiorite. The hardness of Granulite is 6-7 and that of Granodiorite is 6. The types of Granulite are Not Available whereas types of Granodiorite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Granodiorite is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Granodiorite is 0.79 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 Granodiorite is heat resistant, wear resistant.
