Formation
Formation
Monzonite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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.

All about Monzonite and Jasperoid Properties
Know all about Monzonite and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Monzonite belongs to Igneous Rocks while Jasperoid belongs to Sedimentary Rocks.Texture of Monzonite is Phaneritic whereas that of Jasperoid is Earthy. Monzonite appears Shiny and Jasperoid appears Glassy or Pearly. The luster of Monzonite is subvitreous to dull while that of Jasperoid is vitreous and pearly. Monzonite is available in black, brown, light to dark grey, white colors whereas Jasperoid is available in black, brown, green, grey, pink, white colors. The commercial uses of Monzonite are creating artwork and that 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).
