5 Formation

5.1 Formation

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

Anthracite vs Dolomite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Anthracite and Dolomite Reserves. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Anthracite vs Dolomite information and Anthracite vs Dolomite characteristics in the upcoming sections.

More about Anthracite and Dolomite

Here you can know more about Anthracite and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Dolomite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals 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 Anthracite vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Anthracite is Veined or Pebbled and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Anthracite vs Dolomite. The hardness of Anthracite is 1-1.5 and that of Dolomite is 3.5-4. The types of Anthracite are Semi-anthracite and Meta-anthracite 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 Anthracite is black while that of Dolomite is white. The specific heat capacity of Anthracite is 1.32 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.Anthracite is heat resistant, water resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
