Formation

Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.   
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 Peridotite and Jasperoid Properties

Know all about Peridotite and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Peridotite belongs to Igneous Rocks while Jasperoid belongs to Sedimentary Rocks.Texture of Peridotite is Phaneritic whereas that of Jasperoid is Earthy. Peridotite appears Rough and Shiny and Jasperoid appears Glassy or Pearly. The luster of Peridotite is shiny while that of Jasperoid is vitreous and pearly. Peridotite is available in dark greenish - grey colors whereas Jasperoid is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds 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).
