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.

Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

Oil shale vs Chalk 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 Chalk Reserves. Oil Shale is a fine-grained sedimentary rock from which oil is extracted. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. 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 Chalk information and Oil shale vs Chalk characteristics in the upcoming sections.

More about Oil shale and Chalk

Here you can know more about Oil shale and Chalk. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Chalk 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 Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Chalk, 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, Chalk is available in grey, white, yellow colors. Appearance of Oil shale is Muddy and that of Chalk is Soft. Properties of rock is another aspect for Oil shale vs Chalk. The hardness of Oil shale is 2-3 and that of Chalk is 1. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Chalk 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 and Chalk is white. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Chalk is 0.90 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 Chalk is heat resistant.
