Formation

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

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 Limestone and Arkose Properties

Know all about Limestone and Arkose properties here. All properties of rocks are important as they define the type of rock and its application. Limestone and Arkose belong to Sedimentary Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Arkose is Clastic. Limestone appears Rough and Banded and Arkose appears Rough and Dull. The luster of Limestone is dull to pearly while that of Arkose is dull. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas Arkose is available in reddish brown colors. The commercial uses 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 and that of Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones.
