5 Formation

5.1 Formation

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

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 Evaporite and Lignite Properties

Know all about Evaporite and Lignite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Lignite belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Lignite is Amorphous, Glassy. Evaporite appears Glassy, Vesicular and Foilated and Lignite appears Veined or Pebbled. The luster of Evaporite is subvitreous to dull while that of Lignite is dull to vitreous to submetallic. Evaporite is available in colourless, green, grey, silver, white colors whereas Lignite is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite and that of Lignite are electricity generation.
