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.

Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

Dolomite vs Coal 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 Coal Reserves. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. 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 Coal information and Dolomite vs Coal characteristics in the upcoming sections.

Dolomite vs Coal 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 Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Coal. Learn more about Dolomite vs Coal in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Dolomite and Coal, 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 Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.

More about Dolomite and Coal

Here you can know more about Dolomite and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Coal consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Coal, 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, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Dolomite is Glassy or Pearly and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Dolomite vs Coal. The hardness of Dolomite is 3.5-4 and that of Coal is 1-1.5. The types of Dolomite are Boninite and Jasperoid whereas types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. 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 Coal is black. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Coal 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 Coal is heat resistant.
