1 Definition

1.1 Definition

Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals

Vogesite is a porphyritic alkaline igneous rock and is a variety of Lamprophyre which is dominated by essential amphibole, usually hornblende, and potassic feldspar

5 Formation

5.1 Formation

Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

All about Pumice and Vogesite Properties

Know all about Pumice and Vogesite properties here. All properties of rocks are important as they define the type of rock and its application. Pumice and Vogesite belong to Igneous Rocks.Texture of Pumice is Vesicular whereas that of Vogesite is Porphyritic. Pumice appears Vesicular and Vogesite appears Dull, Banded and Foilated. The luster of Pumice is earthy while that of Vogesite is subvitreous to dull. Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors whereas Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Pumice are as a traction material on snow-covered roads, as an abrasive in pencil erasers, fine abrasive used for polishing, manufacture of soap, solvents, dyes, plastics and fibres, used in aquariums and that 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).
