5 Formation

5.1 Formation

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

Rhyodacite 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 Rhyodacite Properties

Know all about Evaporite and Rhyodacite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Rhyodacite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Rhyodacite is Earthy. Evaporite appears Glassy, Vesicular and Foilated and Rhyodacite appears Skeletal. The luster of Evaporite is subvitreous to dull while that of Rhyodacite is greasy to dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Rhyodacite is available in black to grey, dark greenish - 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 Rhyodacite are cemetery markers, creating artwork.
