Definition
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
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 Ganister and Talc carbonate Properties
Know all about Ganister and Talc carbonate properties here. All properties of rocks are important as they define the type of rock and its application. Ganister belongs to Sedimentary Rocks while Talc carbonate belongs to Metamorphic Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Talc carbonate is Very Soft. Ganister appears Rough and Talc carbonate appears Soft. The luster of Ganister is dull while that of Talc carbonate is pearly. Ganister 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 Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones and that of Talc carbonate are manufacturing of baby powder.
