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
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt

Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

All about Vogesite and Gabbro Properties
Know all about Vogesite and Gabbro properties here. All properties of rocks are important as they define the type of rock and its application. Vogesite and Gabbro belong to Igneous Rocks.Texture of Vogesite is Porphyritic whereas that of Gabbro is Phaneritic. Vogesite appears Dull, Banded and Foilated and Gabbro appears Veined and Shiny. The luster of Vogesite is subvitreous to dull while that of Gabbro is not available. Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Gabbro is available in dark grey to black 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 Gabbro are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
