Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
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
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

All about Basanite and Vogesite Properties
Know all about Basanite and Vogesite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite and Vogesite belong to Igneous Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Vogesite is Porphyritic. Basanite appears Glassy or Pearly and Vogesite appears Dull, Banded and Foilated. The luster of Basanite is waxy and dull while that of Vogesite is subvitreous to dull. Basanite is available in black, brown, green, grey, red, white colors whereas Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses 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 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).
