Formation
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 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.

Talc carbonate 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. Talc carbonate vs Oil shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Oil shale. Learn more about Talc carbonate vs Oil shale in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Oil shale include Not yet used. Due to some exceptional properties of Talc carbonate and Oil shale, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Oil shale include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock.
More about Talc carbonate and Oil shale
Here you can know more about Talc carbonate and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Oil shale consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium 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 Talc carbonate vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in colourless, grey, white colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Talc carbonate is Soft and that of Oil shale is Muddy. Properties of rock is another aspect for Talc carbonate vs Oil shale. The hardness of Talc carbonate is 1-2 and that of Oil shale is 2-3. The types of Talc carbonate 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 Talc carbonate and Oil shale is white. The specific heat capacity of Talc carbonate is 0.92 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.Talc carbonate is heat resistant, wear resistant whereas Oil shale is heat resistant, impact resistant.
