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

Etymology
From French, Greek eklogē selection with reference to the selective content of the rock + -ite1
From a sediment left after the evaporation

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

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