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.
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.

Oil shale vs Gossan 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 Gossan Reserves. Oil Shale is a fine-grained sedimentary rock from which oil is extracted. Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.. 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 Gossan information and Oil shale vs Gossan characteristics in the upcoming sections.

More about Oil shale and Gossan

Here you can know more about Oil shale and Gossan. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Gossan 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 Gossan includes Apatite, Augite, Biotite, Bronzite, Calcite, Chert, Epidote, Feldspar, Hornblende, Micas, Plagioclase, Pyroxene, Quartz, Sulfides, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Gossan, 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, Gossan is available in brown, brown- black, gold, green, rust colors. Appearance of Oil shale is Muddy and that of Gossan is Dull and Banded. Properties of rock is another aspect for Oil shale vs Gossan. The hardness of Oil shale is 2-3 and that of Gossan is 4-5. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Gossan are Translocated gossan and Leakage gossan. 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 Gossan is white to grey. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Gossan is 0.24 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 Gossan is heat resistant, impact resistant, pressure resistant.
