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
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions

Etymology
From the variety of Lamprophyre Greek lampros bright and shining + porphureos purple
From the Lherz Massif, an alpine peridotite complex, at Étang de Lers, near Massat in the French Pyrenees; Lherz is the archaic spelling of this location

Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Lherzolite 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.

All about Vogesite and Lherzolite Properties
Know all about Vogesite and Lherzolite properties here. All properties of rocks are important as they define the type of rock and its application. Vogesite and Lherzolite belong to Igneous Rocks.Texture of Vogesite is Porphyritic whereas that of Lherzolite is Grenue. Vogesite appears Dull, Banded and Foilated and Lherzolite appears Glassy, Vesicular and Foilated. The luster of Vogesite and Lherzolite is subvitreous to dull. Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Lherzolite is available in black, dark greenish - grey, green, pink, purple 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 Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums.
