Formation

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.  
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

Oil shale vs Blueschist 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 Oil shale and Blueschist Reserves. Oil Shale is a fine-grained sedimentary rock from which oil is extracted. Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature. 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 Oil shale vs Blueschist information and Oil shale vs Blueschist characteristics in the upcoming sections.

More about Oil shale and Blueschist

Here you can know more about Oil shale and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Blueschist 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 Blueschist includes Albite, Chlorite, Epidote, Garnet, Glaucophane, Lawsonite, Muscovite or Illite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Blueschist, 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, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Oil shale is Muddy and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Oil shale vs Blueschist. The hardness of Oil shale is 2-3 and that of Blueschist is 3.5-4. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Blueschist are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oil shale is white while that of Blueschist is white to grey. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Blueschist is 0.84 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 Blueschist is impact resistant, pressure resistant.
