Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

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