Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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 Charnockite and Oil shale
Here you can know more about Charnockite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Oil shale consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz 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 Igneous Rocks. When we have to compare Charnockite vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Charnockite is Veined or Pebbled and that of Oil shale is Muddy. Properties of rock is another aspect for Charnockite vs Oil shale. The hardness of Charnockite is 6-7 and that of Oil shale is 2-3. The types of Charnockite are Enderbite 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 Charnockite and Oil shale is white. The specific heat capacity of Charnockite is Not Available 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.Charnockite is heat resistant, wear resistant whereas Oil shale is heat resistant, impact resistant.
