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