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.
  
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Talc carbonate vs Dolomite 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 Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Dolomite. Learn more about Talc carbonate vs Dolomite in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Talc carbonate and Dolomite, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Dolomite 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, Production of glass and ceramics, Serves as an oil and gas reservoir rock.
More about Talc carbonate and Dolomite
Here you can know more about Talc carbonate and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Dolomite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Dolomite, 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, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Talc carbonate is Soft and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Talc carbonate vs Dolomite. The hardness of Talc carbonate is 1-2 and that of Dolomite is 3.5-4. The types of Talc carbonate are Not Available whereas types of Dolomite are Boninite and Jasperoid. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Talc carbonate and Dolomite is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Dolomite 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.Talc carbonate is heat resistant, wear resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
