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