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