Formation

Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.

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

All about Gritstone and Limestone Properties

Know all about Gritstone and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Gritstone and Limestone belong to Sedimentary Rocks.Texture of Gritstone is Earthy whereas that of Limestone is Clastic or Non-Clastic. Gritstone appears Layered and Foliated and Limestone appears Rough and Banded. The luster of Gritstone is dull while that of Limestone is dull to pearly. Gritstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow 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 Gritstone are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, 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.
