Vogesite and Talc carbonate

Vogesite

Talc carbonate

Definition

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

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

Formation

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

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 Vogesite and Talc carbonate Properties

Know all about Vogesite and Talc carbonate properties here. All properties of rocks are important as they define the type of rock and its application. Vogesite belongs to Igneous Rocks while Talc carbonate belongs to Metamorphic Rocks.Texture of Vogesite is Porphyritic whereas that of Talc carbonate is Very Soft. Vogesite appears Dull, Banded and Foilated and Talc carbonate appears Soft. The luster of Vogesite is subvitreous to dull while that of Talc carbonate is pearly. Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Talc carbonate is available in colourless, grey, white colors. The commercial uses 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) and that of Talc carbonate are manufacturing of baby powder.
