Formation
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.

Lignite vs Lignite 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. Lignite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Lignite. Learn more about Lignite vs Lignite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Lignite and Lignite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Lignite include For road aggregate, Steel production.
More about Lignite and Lignite
Here you can know more about Lignite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Lignite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Lignite is not available. You can also check out the list of all . When we have to compare Lignite vs Lignite, 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, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Lignite is Veined or Pebbled and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Lignite vs Lignite. Hardness of Lignite and Lignite is 1. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite 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 Lignite and Lignite is black. The specific heat capacity of Lignite is 1.26 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.Lignite is heat resistant whereas Lignite is heat resistant.
