Vogesite and Icelandite
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
Icelandite belongs to volcanic igneous rocks which is rich in iron and belongs to andesite rock

Formation
Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Icelandite 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 Icelandite Properties
Know all about Vogesite and Icelandite properties here. All properties of rocks are important as they define the type of rock and its application. Vogesite and Icelandite belong to Igneous Rocks.Texture of Vogesite is Porphyritic whereas that of Icelandite is Aphanitic to Porphyritic. Vogesite appears Dull, Banded and Foilated and Icelandite appears Dull and Soft. The luster of Vogesite is subvitreous to dull while that of Icelandite is vitreous. Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Icelandite is available in bluish - grey, grey, pink, 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 Icelandite are cemetery markers, creating artwork.
