Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

Dolomite vs Anthracite 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 Anthracite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Anthracite. Learn more about Dolomite vs Anthracite in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Anthracite include Not yet used. Due to some exceptional properties of Dolomite and Anthracite, 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 Anthracite include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Dolomite and Anthracite
Here you can know more about Dolomite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Anthracite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all . When we have to compare Dolomite vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Dolomite is Glassy or Pearly and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Dolomite vs Anthracite. The hardness of Dolomite is 3.5-4 and that of Anthracite is 1-1.5. The types of Dolomite are Boninite and Jasperoid whereas types of Anthracite are Semi-anthracite and Meta-anthracite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite is white while that of Anthracite is black. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Anthracite is 1.32 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 Anthracite is heat resistant, water resistant.
