Definition
Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

Archaeological Significance
Formation
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

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