Archaeological Significance
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.
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 vs Oil 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. Granulite vs Oil shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Oil shale. Learn more about Granulite vs Oil shale 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 Oil shale include . Due to some exceptional properties of Granulite and Oil shale, 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 Oil shale include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock.
More about Granulite and Oil shale
Here you can know more about Granulite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Oil shale 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 Oil 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 Metamorphic Rocks. When we have to compare Granulite vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Granulite is Veined or Pebbled and that of Oil shale is Muddy. Properties of rock is another aspect for Granulite vs Oil shale. The hardness of Granulite is 6-7 and that of Oil shale is 2-3. The types of Granulite are Metamorphic rock whereas types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Oil shale is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Oil 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.Granulite is heat resistant, wear resistant whereas Oil shale is heat resistant, impact resistant.
