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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Gritstone and Talc carbonate Properties
Know all about Gritstone and Talc carbonate properties here. All properties of rocks are important as they define the type of rock and its application. Gritstone belongs to Sedimentary Rocks while Talc carbonate belongs to Metamorphic Rocks.Texture of Gritstone is Earthy whereas that of Talc carbonate is Very Soft. Gritstone appears Layered and Foliated and Talc carbonate appears Soft. The luster of Gritstone is dull while that of Talc carbonate is pearly. Gritstone and Talc carbonate 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 Talc carbonate are manufacturing of baby powder.
