Formation

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.   
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

All about Jasperoid and Phonolite Properties

Know all about Jasperoid and Phonolite properties here. All properties of rocks are important as they define the type of rock and its application. Jasperoid belongs to Sedimentary Rocks while Phonolite belongs to Igneous Rocks.Texture of Jasperoid is Earthy whereas that of Phonolite is Granular. Jasperoid appears Glassy or Pearly and Phonolite appears Banded and Foilated. The luster of Jasperoid is vitreous and pearly while that of Phonolite is greasy to dull. Jasperoid is available in black, brown, colourless, green, grey, pink, white colors whereas Phonolite is available in brown, buff, cream, green, grey, pink, white 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 Phonolite are cemetery markers, creating artwork.
