Definition
Websterite is ultramafic and ultrabasic rock that consists of roughly equal proportions of orthopyroxene and clinopyroxene. It is a special type of pyroxenite.
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

Formation
Websterite can be formed as cumulates in ultramafic intrusions by accumulation of pyroxene crystals at the base of the lava chamber.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Websterite and Evaporite Properties
Know all about Websterite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Websterite belongs to Igneous Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Websterite is Clastic, Granular, Phaneritic, Porphyritic whereas that of Evaporite is Earthy. Websterite appears Layered, Banded, Veined and Shiny and Evaporite appears Glassy, Vesicular and Foilated. The luster of Websterite is dull to vitreous to submetallic while that of Evaporite is subvitreous to dull. Websterite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses of Websterite are cemetery markers, commemorative tablets, creating artwork, laboratory bench tops, jewelry, sea defence, tombstones and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
