Formation

Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.   
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

All about Evaporite and Amphibolite Properties

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