Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

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

All about Talc carbonate and Limestone Properties
Know all about Talc carbonate and Limestone 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 Limestone belongs to Sedimentary Rocks.Texture of Talc carbonate is Very Soft whereas that of Limestone is Clastic or Non-Clastic. Talc carbonate appears Soft and Limestone appears Rough and Banded. The luster of Talc carbonate is pearly while that of Limestone is dull to pearly. Talc carbonate is available in grey, white 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 Talc carbonate are manufacturing of baby powder 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.
