5 Formation

5.1 Formation

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

Tephrite 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 Tephrite Properties

Know all about Evaporite and Tephrite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Tephrite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Tephrite is Aphanitic to Porphyritic. Evaporite appears Glassy, Vesicular and Foilated and Tephrite appears Vesicular. The luster of Evaporite and Tephrite is subvitreous to dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Tephrite is available in black, brown, colourless, green, grey, white 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 Tephrite are production of lime, soil conditioner.
