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.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

All about Jasperoid and Soapstone Properties
Know all about Jasperoid and Soapstone properties here. All properties of rocks are important as they define the type of rock and its application. Jasperoid belongs to Sedimentary Rocks while Soapstone belongs to Metamorphic Rocks.Texture of Jasperoid is Earthy whereas that of Soapstone is Polished. Jasperoid appears Glassy or Pearly and Soapstone appears Dull, Banded and Foilated. The luster of Jasperoid is vitreous and pearly while that of Soapstone is greasy. Jasperoid is available in black, brown, colourless, green, grey, pink, white colors whereas Soapstone is available in black, black to grey, 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 Soapstone are cemetery markers, creating artwork, gemstone, jewelry, manufacture of soap, solvents, dyes, plastics and fibres, production of lime, source of magnesia (mgo).
