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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

All about Soapstone and Laterite Properties
Know all about Soapstone and Laterite properties here. All properties of rocks are important as they define the type of rock and its application. Soapstone belongs to Metamorphic Rocks while Laterite belongs to Sedimentary Rocks.Texture of Soapstone is Polished whereas that of Laterite is Earthy, Massive, Porphyritic. Soapstone appears Dull, Banded and Foilated and Laterite appears Rough and Banded. The luster of Soapstone is greasy while that of Laterite is dull. Soapstone is available in black, black to grey, green, grey colors whereas Laterite is available in brown, buff, red 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 Laterite are an oil and gas reservoir, source of bauxite, used in aquariums.
