Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

More about Charnockite and Lignite

Here you can know more about Charnockite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Lignite consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz and mineral content of Lignite includes . You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Charnockite is Veined or Pebbled and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Charnockite vs Lignite. The hardness of Charnockite is 6-7 and that of Lignite is 1. The types of Charnockite are Enderbite 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 Charnockite is white while that of Lignite is black. The specific heat capacity of Charnockite is 0.84 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.Charnockite is heat resistant, wear resistant whereas Lignite is heat resistant.
