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

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

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