Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar

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.
Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

All about Talc carbonate and Minette Properties
Know all about Talc carbonate and Minette 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 Minette belongs to Igneous Rocks.Texture of Talc carbonate is Very Soft whereas that of Minette is Porphyritic. Talc carbonate appears Soft and Minette appears Dull, Banded and Foilated. The luster of Talc carbonate is pearly while that of Minette is subvitreous to dull. Talc carbonate is available in colourless, grey, white colors whereas Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Talc carbonate are manufacturing of baby powder and that of Minette are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
