Talc carbonate and Ganister


Ganister and Talc carbonate


Definition

Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.   
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.

Formation

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.   
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

All about Talc carbonate and Ganister Properties

Know all about Talc carbonate and Ganister 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 Ganister belongs to Sedimentary Rocks.Texture of Talc carbonate is Very Soft whereas that of Ganister is Clastic, Granular, Rough. Talc carbonate appears Soft and Ganister appears Rough. The luster of Talc carbonate is pearly while that of Ganister is dull. Talc carbonate is available in colourless, grey, white colors whereas Ganister 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 Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones.
