5 Formation
5.1 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.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

All about Lignite and Anorthosite Properties

Know all about Lignite and Anorthosite properties here. All properties of rocks are important as they define the type of rock and its application. Lignite belongs to Sedimentary Rocks while Anorthosite belongs to Igneous Rocks.Texture of Lignite is Amorphous, Glassy whereas that of Anorthosite is Foliated, Glassy. Lignite appears Veined or Pebbled and Anorthosite appears Layered, Banded, Veined and Shiny. The luster of Lignite is dull to vitreous to submetallic while that of Anorthosite is pearly to subvitreous. Lignite is available in black, brown, dark brown, grey, light to dark grey colors whereas Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. The commercial uses of Lignite are electricity generation and that of Anorthosite are creating artwork, curling.
