Definition
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution
It is a metamorphic magnesium rich rock because it is composed of the mineral talc

Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

All about Evaporite and Soapstone Properties
Know all about Evaporite and Soapstone properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Soapstone belongs to Metamorphic Rocks.Texture of Evaporite is Earthy whereas that of Soapstone is Polished. Evaporite appears Glassy, Vesicular and Foilated and Soapstone appears Dull, Banded and Foilated. The luster of Evaporite is subvitreous to dull while that of Soapstone is greasy. Evaporite is available in green, grey, silver, white colors whereas Soapstone is available in black, black to grey, green, 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 Soapstone are cemetery markers, creating artwork, gemstone, jewelry, manufacture of soap, solvents, dyes, plastics and fibres, production of lime, source of magnesia (mgo).
