Formation

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.

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

All about Amphibolite and Evaporite Properties

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