Evaporite and Wehrlite


Definition

Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

Formation

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

All about Wehrlite and Evaporite Properties

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