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
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

All about Vogesite and Basanite Properties
Know all about Vogesite and Basanite properties here. All properties of rocks are important as they define the type of rock and its application. Vogesite and Basanite belong to Igneous Rocks.Texture of Vogesite is Porphyritic whereas that of Basanite is Aphanitic to Porphyritic. Vogesite appears Dull, Banded and Foilated and Basanite appears Glassy or Pearly. The luster of Vogesite is subvitreous to dull while that of Basanite is waxy and dull. Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Basanite is available in black, brown, green, grey, red, 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 Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms.
