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.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Arkose and Limestone Properties
Know all about Arkose and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Arkose and Limestone belong to Sedimentary Rocks.Texture of Arkose is Clastic whereas that of Limestone is Clastic or Non-Clastic. Arkose appears Rough and Dull and Limestone appears Rough and Banded. The luster of Arkose is dull while that of Limestone is dull to pearly. Arkose is available in reddish brown colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses of Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
