Vogesite and Pyrolite


Definition

Definition
Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt   
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

Formation
Pyrolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.   
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

All about Pyrolite and Vogesite Properties

Know all about Pyrolite and Vogesite properties here. All properties of rocks are important as they define the type of rock and its application. Pyrolite and Vogesite belong to Igneous Rocks.Texture of Pyrolite is Phaneritic whereas that of Vogesite is Porphyritic. Pyrolite appears Rough and Shiny and Vogesite appears Dull, Banded and Foilated. The luster of Pyrolite is shiny while that of Vogesite is subvitreous to dull. Pyrolite is available in dark greenish - grey colors whereas Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Pyrolite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds 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).
