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.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

All about Soapstone and Diamictite Properties
Know all about Soapstone and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Soapstone belongs to Metamorphic Rocks while Diamictite belongs to Sedimentary Rocks.Texture of Soapstone is Polished whereas that of Diamictite is Clastic. Soapstone appears Dull, Banded and Foilated and Diamictite appears Banded. The luster of Soapstone is greasy while that of Diamictite is grainy, pearly and vitreous. Soapstone is available in black, black to grey, green, grey colors whereas Diamictite is available in brown, buff 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 Diamictite are commemorative tablets, creating artwork, production of lime.
