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.
  
Norite 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.

Granulite vs Norite 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 Norite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Norite. Learn more about Granulite vs Norite 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 Norite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Granulite and Norite, 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 Norite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Granulite and Norite
Here you can know more about Granulite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Norite 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 Norite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Norite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Norite is available in dark grey to black colors. Appearance of Granulite is Veined or Pebbled and that of Norite is Veined and Shiny. Properties of rock is another aspect for Granulite vs Norite. The hardness of Granulite is 6-7 and that of Norite is 7. The types of Granulite are Not Available whereas types of Norite 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 Norite is black. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Norite 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 Norite is impact resistant, pressure resistant, wear resistant.
