Vogesite and Marl
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
Marl is an unconsolidated sedimentary rock consisting of clay and lime

Formation
Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Marl forms when very fine-grained clay particles are deposited in water which settles at the bottom of water bodies and are compacted by overlying sediment; the water squeezes out and hence forming Marl rock.

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