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.
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

All about Gritstone and Whiteschist Properties
Know all about Gritstone and Whiteschist properties here. All properties of rocks are important as they define the type of rock and its application. Gritstone belongs to Sedimentary Rocks while Whiteschist belongs to Metamorphic Rocks.Texture of Gritstone is Earthy whereas that of Whiteschist is Foliated. Gritstone appears Layered and Foliated and Whiteschist appears Banded and Foilated. The luster of Gritstone is dull while that of Whiteschist is subvitreous to dull. Gritstone and Whiteschist are available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, 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 Whiteschist are creating artwork, gemstone, jewelry, production of lime.
