Vogesite and Diabase


Diabase and Vogesite


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   
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar

Formation

Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.   
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

All about Vogesite and Diabase Properties

Know all about Vogesite and Diabase properties here. All properties of rocks are important as they define the type of rock and its application. Vogesite and Diabase belong to Igneous Rocks.Texture of Vogesite is Porphyritic whereas that of Diabase is Aphanitic, Granular. Vogesite appears Dull, Banded and Foilated and Diabase appears Vesicular. The luster of Vogesite is subvitreous to dull while that of Diabase is not available. Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Diabase is available in dark grey to black 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 Diabase are an oil and gas reservoir, cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
