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.

Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

Oil shale vs Lignite 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 Lignite Reserves. Oil Shale is a fine-grained sedimentary rock from which oil is extracted. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. 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 Lignite information and Oil shale vs Lignite characteristics in the upcoming sections.

Oil shale vs Lignite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Oil shale vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oil shale and Properties of Lignite. Learn more about Oil shale vs Lignite in the next section. The interior uses of Oil shale include Not yet used whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Oil shale and Lignite, 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 Lignite include For road aggregate, Steel production.

More about Oil shale and Lignite

Here you can know more about Oil shale and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Lignite 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 Lignite is not available. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Lignite, 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, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Oil shale is Muddy and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Oil shale vs Lignite. The hardness of Oil shale is 2-3 and that of Lignite is 1. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. 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 Lignite is black. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Lignite is 1.26 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 Lignite is heat resistant.
