5 Formation

5.1 Formation

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.

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

All about Arkose and Evaporite Properties

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