1 Definition

1.1 Definition

A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

5 Formation

5.1 Formation

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

Felsite 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 Felsite Properties

Know all about Evaporite and Felsite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Felsite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Felsite is Arborescent Patterned, Vitreous. Evaporite appears Glassy, Vesicular and Foilated and Felsite appears Layered, Banded, Veined and Shiny. The luster of Evaporite is subvitreous to dull while that of Felsite is vitreous. Evaporite is available in colourless, green, grey, silver, white colors whereas Felsite is available in black, blue, brown, green, orange, red, tan, yellow 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 Felsite are mirror, jewelry.
