Archaeological Significance
Formation
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 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 vs Granulite 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. Granodiorite vs Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granodiorite and Properties of Granulite. Learn more about Granodiorite vs Granulite in the next section. The interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Granodiorite and Granulite, they have various applications in construction industry. The uses of Granodiorite in construction industry include As dimension stone and that of Granulite include As dimension stone, Building houses or walls.
More about Granodiorite and Granulite
Here you can know more about Granodiorite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Granulite consists of mineral content and compound content. The mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Granodiorite is available in black, grey, orange, pink, white colors whereas, Granulite is available in black, brown colors. Appearance of Granodiorite is Veined or Pebbled and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Granodiorite vs Granulite. The hardness of Granodiorite is 6 and that of Granulite is 6-7. The types of Granodiorite are Granodiorite whereas types of Granulite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granodiorite and Granulite is white. The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Granulite is 0.14 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granodiorite is heat resistant, wear resistant whereas Granulite is heat resistant, wear resistant.
