5 Formation

5.1 Formation

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 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.

More about Anthracite and Oil shale

Here you can know more about Anthracite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Oil shale consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Oil shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Anthracite is Veined or Pebbled and that of Oil shale is Muddy. Properties of rock is another aspect for Anthracite vs Oil shale. The hardness of Anthracite is 1-1.5 and that of Oil shale is 2-3. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anthracite is black while that of Oil shale is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Oil shale is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Anthracite is heat resistant, water resistant whereas Oil shale is heat resistant, impact resistant.
