5 Formation

5.1 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.

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

More about Oil shale and Pseudotachylite

Here you can know more about Oil shale and Pseudotachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Pseudotachylite 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 Pseudotachylite includes Iron Oxides, Pyroxene, Quartz, Stishovite, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Pseudotachylite, 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, Pseudotachylite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Oil shale is Muddy and that of Pseudotachylite is Dull and Soft. Properties of rock is another aspect for Oil shale vs Pseudotachylite. The hardness of Oil shale is 2-3 and that of Pseudotachylite is 7. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Pseudotachylite 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 is white while that of Pseudotachylite is light to dark brown. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Pseudotachylite is 0.92 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 Pseudotachylite is heat resistant.
