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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Jasperoid and Boninite Properties
Know all about Jasperoid and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Jasperoid belongs to Sedimentary Rocks while Boninite belongs to Igneous Rocks.Texture of Jasperoid is Earthy whereas that of Boninite is Aphanitic to Porphyritic. Jasperoid appears Glassy or Pearly and Boninite appears Dull and Soft. The luster of Jasperoid is vitreous and pearly while that of Boninite is vitreous. Jasperoid is available in black, brown, colourless, green, grey, pink, white colors whereas Boninite is available in bluish - grey, brown, colourless, green, 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 Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
