Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

All about Evaporite and Arkose Properties
Know all about Evaporite and Arkose properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Arkose belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Arkose is Clastic. Evaporite appears Glassy, Vesicular and Foilated and Arkose appears Rough and Dull. The luster of Evaporite is subvitreous to dull while that of Arkose is dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Arkose is available in reddish brown 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 Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones.
