More about Coal and Lignite
Here you can know more about Coal and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Lignite consists of mineral content and compound content. The 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 and mineral content of Lignite is not available. You can also check out the list of all Sedimentary Rocks. When we have to compare Coal vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Coal is Veined or Pebbled and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Coal vs Lignite. The hardness of Coal is 1-1.5 and that of Lignite is 1. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Coal and Lignite is black. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Lignite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Coal is heat resistant whereas Lignite is heat resistant.
