Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

All about Evaporite and Coal Properties
Know all about Evaporite and Coal properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Coal belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Coal is Amorphous, Glassy. Evaporite appears Glassy, Vesicular and Foilated and Coal appears Veined or Pebbled. The luster of Evaporite is subvitreous to dull while that of Coal is dull to vitreous to submetallic. Evaporite is available in colourless, green, grey, silver, white colors whereas Coal 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 Coal are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
