Formation

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

Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

All about Evaporite and Jasperoid Properties

Know all about Evaporite and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Jasperoid belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Jasperoid is Earthy. Evaporite appears Glassy, Vesicular and Foilated and Jasperoid appears Glassy or Pearly. The luster of Evaporite is subvitreous to dull while that of Jasperoid is vitreous and pearly. Evaporite is available in green, grey, silver, white colors whereas Jasperoid is available in black, brown, green, grey, pink, white 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 Jasperoid are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
