Archaeological Significance
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.
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.

More about Lignite and Whiteschist
Here you can know more about Lignite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Whiteschist consists of mineral content and compound content. The mineral content of Lignite includes and mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Whiteschist, 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, Whiteschist is available in green, grey, white colors. Appearance of Lignite is Veined or Pebbled and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Lignite vs Whiteschist. The hardness of Lignite is 1 and that of Whiteschist is 1.5. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Whiteschist are -. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lignite is black while that of Whiteschist is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Whiteschist is 0.92 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 Whiteschist is heat resistant.
