5 Formation
5.1 Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

Skarn vs Oil shale Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Skarn and Oil shale Reserves. Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin. Oil Shale is a fine-grained sedimentary rock from which oil is extracted. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Skarn vs Oil shale information and Skarn vs Oil shale characteristics in the upcoming sections.

Skarn 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. Skarn vs Oil shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Skarn and Properties of Oil shale. Learn more about Skarn vs Oil shale in the next section. The interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Oil shale include Not yet used. Due to some exceptional properties of Skarn and Oil shale, they have various applications in construction industry. The uses of Skarn in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Gold and silver production, Manufacture of magnesium and dolomite refractories and that of Oil shale include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock.

More about Skarn and Oil shale

Here you can know more about Skarn and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Oil shale consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite 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 Skarn vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Skarn is available in black, brown, colourless, green, grey, white colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Skarn is Dull and that of Oil shale is Muddy. Properties of rock is another aspect for Skarn vs Oil shale. The hardness of Skarn is 6.5 and that of Oil shale is 2-3. The types of Skarn are Endoskarns 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 Skarn is light to dark brown while that of Oil shale is white. The specific heat capacity of Skarn is 0.92 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.Skarn is heat resistant whereas Oil shale is heat resistant, impact resistant.
