Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
  
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Formation
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
  
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.

Whiteschist 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. Whiteschist vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Whiteschist and Properties of Lignite. Learn more about Whiteschist vs Lignite in the next section. The interior uses of Whiteschist include Decorative aggregates and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Whiteschist and Lignite, they have various applications in construction industry. The uses of Whiteschist in construction industry include For road aggregate and that of Lignite include For road aggregate, Steel production.
More about Whiteschist and Lignite
Here you can know more about Whiteschist and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Lignite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Lignite is not available. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in colourless, green, grey, white colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Whiteschist is Banded and Foilated and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Whiteschist vs Lignite. The hardness of Whiteschist is 1.5 and that of Lignite is 1. The types of Whiteschist are Not Available 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 Whiteschist is white while that of Lignite is black. The specific heat capacity of Whiteschist is 0.92 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.Whiteschist is heat resistant whereas Lignite is heat resistant.
