Vogesite and Oolite
Definition
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
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Formation
Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

All about Vogesite and Oolite Properties
Know all about Vogesite and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Vogesite belongs to Igneous Rocks while Oolite belongs to Sedimentary Rocks.Texture of Vogesite is Porphyritic whereas that of Oolite is Clastic or Non-Clastic. Vogesite appears Dull, Banded and Foilated and Oolite appears Rounded and Rough. The luster of Vogesite is subvitreous to dull while that of Oolite is pearly to shiny. Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow 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 Oolite are creating artwork, jewelry, used in aquariums.
