Formation
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.
Sovites are formed due to low degrees of partial melting of rocks.

All about Arkose and Sovite Properties
Know all about Arkose and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Arkose belongs to Sedimentary Rocks while Sovite belongs to Igneous Rocks.Texture of Arkose is Clastic whereas that of Sovite is Granular, Poikiloblastic. Arkose appears Rough and Dull and Sovite appears Dull, Banded and Foilated. The luster of Arkose is dull while that of Sovite is subvitreous to dull. Arkose is available in reddish brown colors whereas Sovite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones and that of Sovite are an oil and gas reservoir, as a feed additive for livestock, creating artwork, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
