Formation
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of 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.

Carbonatite vs Oil shale 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. Carbonatite vs Oil shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Carbonatite and Properties of Oil shale. Learn more about Carbonatite vs Oil shale in the next section. The interior uses of Carbonatite include Decorative aggregates and Interior decoration whereas the interior uses of Oil shale include Not yet used. Due to some exceptional properties of Carbonatite and Oil shale, they have various applications in construction industry. The uses of Carbonatite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Unknown, Unknown and that of Oil shale include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock.
More about Carbonatite and Oil shale
Here you can know more about Carbonatite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Carbonatite and Oil shale consists of mineral content and compound content. The mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite 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 Carbonatite vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Carbonatite is Dull, Banded and Foilated and that of Oil shale is Muddy. Properties of rock is another aspect for Carbonatite vs Oil shale. The hardness of Carbonatite is 3 and that of Oil shale is 2-3. The types of Carbonatite are Not Available 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 Carbonatite and Oil shale is white. The specific heat capacity of Carbonatite 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.Carbonatite is heat resistant, pressure resistant, water resistant whereas Oil shale is heat resistant, impact resistant.
