Definition
Granophyre is a type of granitic rock which consists of intergrown feldspar and quartz crystals in a medium to fine grained groundmass
  
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

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.
  
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

Granophyre vs Shale 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 Shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granophyre and Properties of Shale. Learn more about Granophyre vs Shale 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 Shale include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Granophyre and Shale, they have various applications in construction industry. The uses of Granophyre in construction industry include As dimension stone and that of Shale include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Granophyre and Shale
Here you can know more about Granophyre and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granophyre and Shale consists of mineral content and compound content. The mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz and mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Granophyre vs Shale, 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, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Granophyre is Veined or Pebbled and that of Shale is Muddy. Properties of rock is another aspect for Granophyre vs Shale. The hardness of Granophyre is 6-7 and that of Shale is 3. The types of Granophyre are Not Available whereas types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granophyre and Shale is white. The specific heat capacity of Granophyre is 0.79 kJ/Kg K and that of Shale is 0.39 kJ/Kg K. 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 Shale is heat resistant, impact resistant.
