Formation

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

Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

All about Evaporite and Trachyte Properties

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