Formation

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.

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

All about Trachyte and Evaporite Properties

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