Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

Features
Host Rock for Lead, Traps for subsurface fluids like Oil and Natural Gas., Zinc and Copper Deposits
Easily splits into thin plates, Generally rough to touch, Host Rock for Lead
Archaeological Significance
Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
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 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. Dolomite vs Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Talc carbonate. Learn more about Dolomite vs Talc carbonate in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Dolomite and Talc carbonate, they have various applications in construction industry. The uses of Dolomite 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, Production of glass and ceramics, Serves as an oil and gas reservoir rock and that of Talc carbonate include Source of calcium.
More about Dolomite and Talc carbonate
Here you can know more about Dolomite and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Talc carbonate consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, 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 Dolomite vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, green, grey, pink, white colors whereas, Talc carbonate is available in grey, white colors. Appearance of Dolomite is Glassy or Pearly and that of Talc carbonate is Soft. Properties of rock is another aspect for Dolomite vs Talc carbonate. The hardness of Dolomite is 3.5-4 and that of Talc carbonate is 1-2. The types of Dolomite are Boninite and Jasperoid whereas types of Talc carbonate are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite and Talc carbonate is white. The specific heat capacity of Dolomite is 0.92 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.Dolomite is heat resistant, pressure resistant, wear resistant whereas Talc carbonate is heat resistant, wear resistant.
