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.
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.

Oil shale 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. Oil shale vs Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oil shale and Properties of Granulite. Learn more about Oil shale vs Granulite in the next section. The interior uses of Oil shale include Not yet used 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 Oil shale and Granulite, 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 Granulite include As dimension stone, Building houses or walls.
More about Oil shale and Granulite
Here you can know more about Oil shale and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Granulite 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 Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Oil shale is Muddy and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Oil shale vs Granulite. The hardness of Oil shale is 2-3 and that of Granulite is 6-7. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Granulite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oil shale and Granulite is white. The specific heat capacity of Oil shale is 0.39 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.Oil shale is heat resistant, impact resistant whereas Granulite is heat resistant, wear resistant.
