5 Formation
5.1 Formation
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.
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.

All about Anorthosite and Lignite Properties

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