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.   
The banded iron layers are formed in sea water when oxygen is released by photosynthetic cyano-bacteria. The oxygen then combines with dissolved iron in ocean to form insoluble iron oxides, which precipitated out, forming a thin layer of banded iron formation on ocean floor.

Oil shale vs Banded iron formation 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 Banded iron formation Reserves. Oil Shale is a fine-grained sedimentary rock from which oil is extracted. Banded iron formation are distinctive units of sedimentary rock that are almost always of Precambrian age. 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 Banded iron formation information and Oil shale vs Banded iron formation characteristics in the upcoming sections.

Due to some exceptional properties of Oil shale and Banded iron formation, they have various applications in construction industry. The uses of Oil shale in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock and that of Banded iron formation include As dimension stone, Used for flooring, stair treads, borders and window sills..

More about Oil shale and Banded iron formation

Here you can know more about Oil shale and Banded iron formation. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Banded iron formation 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 Banded iron formation includes Hematite, Magnetite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Banded iron formation, 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, Banded iron formation is available in red, reddish brown colors. Appearance of Oil shale is Muddy and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Oil shale vs Banded iron formation. The hardness of Oil shale is 2-3 and that of Banded iron formation is 5.5-6. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oil shale and Banded iron formation is white. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Banded iron formation is 3.20 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 Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant.
