Dolomite vs 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.

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.
