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.
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

Oil shale vs Anthracite 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 Anthracite Reserves. Oil Shale is a fine-grained sedimentary rock from which oil is extracted. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. 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 Anthracite information and Oil shale vs Anthracite characteristics in the upcoming sections.

More about Oil shale and Anthracite

Here you can know more about Oil shale and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Anthracite 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 Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Anthracite, 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, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Oil shale is Muddy and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Oil shale vs Anthracite. The hardness of Oil shale is 2-3 and that of Anthracite is 1-1.5. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Anthracite are Semi-anthracite and Meta-anthracite. 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 Anthracite is black. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Anthracite is 1.32 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 Anthracite is heat resistant, water resistant.
