Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

Formation
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Whiteschist 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. Whiteschist vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Whiteschist and Properties of Dolomite. Learn more about Whiteschist vs Dolomite in the next section. The interior uses of Whiteschist 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 Whiteschist and Dolomite, they have various applications in construction industry. The uses of Whiteschist in construction industry include For road aggregate 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 Whiteschist and Dolomite
Here you can know more about Whiteschist and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Dolomite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica 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 Whiteschist vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in colourless, green, grey, white colors whereas, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Whiteschist is Banded and Foilated and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Whiteschist vs Dolomite. The hardness of Whiteschist is 1.5 and that of Dolomite is 3.5-4. The types of Whiteschist 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 Whiteschist and Dolomite is white. The specific heat capacity of Whiteschist 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.Whiteschist is heat resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
