Formation
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

All about Jasperoid and Pumice Properties
Know all about Jasperoid and Pumice properties here. All properties of rocks are important as they define the type of rock and its application. Jasperoid belongs to Sedimentary Rocks while Pumice belongs to Igneous Rocks.Texture of Jasperoid is Earthy whereas that of Pumice is Vesicular. Jasperoid appears Glassy or Pearly and Pumice appears Vesicular. The luster of Jasperoid is vitreous and pearly while that of Pumice is earthy. Jasperoid is available in black, brown, colourless, green, grey, pink, white colors whereas Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. The commercial uses of Jasperoid 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 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.
