5 Formation

5.1 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 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 Dolomite and Anthracite Reserves. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. 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 Dolomite vs Anthracite information and Dolomite vs Anthracite characteristics in the upcoming sections.

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 Sedimentary Rocks. 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.
