You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Lignite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Lignite is Veined or Pebbled and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Lignite vs Coal. The hardness of Lignite is 1 and that of Coal is 1-1.5. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite 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 Lignite and Coal is black. The specific heat capacity of Lignite is 1.26 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.Lignite is heat resistant whereas Coal is heat resistant.
