Evaporite and Kenyte
Definition
Definition
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution
Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Kenyte 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 Kenyte Properties
Know all about Evaporite and Kenyte properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Kenyte belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Kenyte is Glassy, Granular. Evaporite appears Glassy, Vesicular and Foilated and Kenyte appears Banded and Foilated. The luster of Evaporite is subvitreous to dull while that of Kenyte is greasy to dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Kenyte is available in brown, buff, cream, green, grey, pink, 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 Kenyte are cemetery markers, creating artwork.
