Evaporite and Ganister
Definition
Definition
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.

Formation
Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

All about Evaporite and Ganister Properties
Know all about Evaporite and Ganister properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Ganister belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Ganister is Clastic, Granular, Rough. Evaporite appears Glassy, Vesicular and Foilated and Ganister appears Rough. The luster of Evaporite is subvitreous to dull while that of Ganister is dull. Evaporite is available in green, grey, silver, white colors whereas Ganister is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow 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 Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones.
