5 Formation

5.1 Formation

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

Picrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Evaporite and Picrite Properties

Know all about Evaporite and Picrite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Picrite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Picrite is Earthy, Rough. Evaporite appears Glassy, Vesicular and Foilated and Picrite appears Rough and Shiny. The luster of Evaporite and Picrite is subvitreous to dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Picrite is available in black, brown, colourless, green, grey, pink, white, yellow 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 Picrite are as a feed additive for livestock, as armour rock for sea walls, metallurgical flux, pottery, source of magnesia (mgo).
