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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Oil shale vs Talc carbonate 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 Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oil shale and Properties of Talc carbonate. Learn more about Oil shale vs Talc carbonate in the next section. The interior uses of Oil shale include Not yet used whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Oil shale and Talc carbonate, 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 Talc carbonate include Source of calcium.
More about Oil shale and Talc carbonate
Here you can know more about Oil shale and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Talc carbonate 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 Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Talc carbonate, 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, Talc carbonate is available in colourless, grey, white colors. Appearance of Oil shale is Muddy and that of Talc carbonate is Soft. Properties of rock is another aspect for Oil shale vs Talc carbonate. The hardness of Oil shale is 2-3 and that of Talc carbonate is 1-2. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Talc carbonate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oil shale and Talc carbonate is white. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Talc carbonate is 0.92 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 Talc carbonate is heat resistant, wear resistant.
