Formation
Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.
Granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks

Oil shale vs Granite 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. Oil shale vs Granite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oil shale and Properties of Granite. Learn more about Oil shale vs Granite in the next section. The interior uses of Oil shale include Not yet used whereas the interior uses of Granite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Oil shale and Granite, they have various applications in construction industry. The uses of Oil shale in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock and that of Granite include As dimension stone.
More about Oil shale and Granite
Here you can know more about Oil shale and Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Granite consists of mineral content and compound content. The mineral content of Oil shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides and mineral content of Granite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Granite, the texture, color and appearance plays an important role in determining the type of rock. Oil shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Granite is available in black, grey, orange, pink, white colors. Appearance of Oil shale is Muddy and that of Granite is Veined or Pebbled. Properties of rock is another aspect for Oil shale vs Granite. The hardness of Oil shale is 2-3 and that of Granite is 6-7. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oil shale and Granite is white. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Granite 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.Oil shale is heat resistant, impact resistant whereas Granite is heat resistant, wear resistant.
