Vogesite and Coal
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
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

Formation
Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

All about Vogesite and Coal Properties
Know all about Vogesite and Coal properties here. All properties of rocks are important as they define the type of rock and its application. Vogesite belongs to Igneous Rocks while Coal belongs to Sedimentary Rocks.Texture of Vogesite is Porphyritic whereas that of Coal is Amorphous, Glassy. Vogesite appears Dull, Banded and Foilated and Coal appears Veined or Pebbled. The luster of Vogesite is subvitreous to dull while that of Coal is dull to vitreous to submetallic. Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Coal is available in black, brown, dark brown, grey, light to dark grey 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 Coal are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
