Formation

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

Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

All about Evaporite and Pyroxenite Properties

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