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
Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals

Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

All about Vogesite and Pegmatite Properties
Know all about Vogesite and Pegmatite properties here. All properties of rocks are important as they define the type of rock and its application. Vogesite and Pegmatite belong to Igneous Rocks.Texture of Vogesite is Porphyritic whereas that of Pegmatite is Pegmatitic. Vogesite appears Dull, Banded and Foilated and Pegmatite appears Layered, Banded, Veined and Shiny. The luster of Vogesite is subvitreous to dull while that of Pegmatite is grainy, pearly and vitreous. Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow 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 Pegmatite are creating artwork, jewelry, source of corundum, tourmalines, beryls and topaz.
