Talc carbonate and Vogesite

Talc carbonate

Vogesite

Definition

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

Vogesite is a porphyritic alkaline igneous rock and is a variety of Lamprophyre which is dominated by essential amphibole, usually hornblende, 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.

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

All about Talc carbonate and Vogesite Properties

Know all about Talc carbonate and Vogesite 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 Vogesite belongs to Igneous Rocks.Texture of Talc carbonate is Very Soft whereas that of Vogesite is Porphyritic. Talc carbonate appears Soft and Vogesite appears Dull, Banded and Foilated. The luster of Talc carbonate is pearly while that of Vogesite is subvitreous to dull. Talc carbonate is available in colourless, grey, white colors whereas Vogesite 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 Vogesite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
