Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
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
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

All about Eclogite and Vogesite Properties
Know all about Eclogite and Vogesite properties here. All properties of rocks are important as they define the type of rock and its application. Eclogite belongs to Metamorphic Rocks while Vogesite belongs to Igneous Rocks.Texture of Eclogite is Earthy whereas that of Vogesite is Porphyritic. Eclogite appears Dull, Banded and Foilated and Vogesite appears Dull, Banded and Foilated. The luster of Eclogite and Vogesite is subvitreous to dull. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Eclogite are creating artwork, gemstone 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).
