Formation

Hornblendite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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

All about Hornblendite and Evaporite Properties

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