Definition
Granophyre is a type of granitic rock which consists of intergrown feldspar and quartz crystals in a medium to fine grained groundmass
  
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine

Formation
Granophyre 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.
  
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.

Granophyre 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. Granophyre vs Norite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granophyre and Properties of Norite. Learn more about Granophyre vs Norite in the next section. The interior uses of Granophyre include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, 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 Granophyre and Norite, they have various applications in construction industry. The uses of Granophyre in construction industry include As dimension stone and that of Norite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Granophyre and Norite
Here you can know more about Granophyre and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granophyre and Norite consists of mineral content and compound content. The mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz and mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Granophyre vs Norite, the texture, color and appearance plays an important role in determining the type of rock. Granophyre is available in black, grey, orange, pink, white colors whereas, Norite is available in dark grey to black colors. Appearance of Granophyre is Veined or Pebbled and that of Norite is Veined and Shiny. Properties of rock is another aspect for Granophyre vs Norite. The hardness of Granophyre is 6-7 and that of Norite is 7. The types of Granophyre 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 Granophyre is white while that of Norite is black. The specific heat capacity of Granophyre is 0.79 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.Granophyre is heat resistant, wear resistant whereas Norite is impact resistant, pressure resistant, wear resistant.
