Formation
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.
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.

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