Evaporite and Eclogite
Definition
Definition
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

Formation
Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

All about Evaporite and Eclogite Properties
Know all about Evaporite and Eclogite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Eclogite belongs to Metamorphic Rocks.Texture of Evaporite is Earthy whereas that of Eclogite is Earthy. Evaporite appears Glassy, Vesicular and Foilated and Eclogite appears Dull, Banded and Foilated. The luster of Evaporite and Eclogite is subvitreous to dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Eclogite is available in black, brown, colourless, green, grey, pink, white 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 Eclogite are creating artwork, gemstone.
