Formation
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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 Benmoreite and Soapstone Properties
Know all about Benmoreite and Soapstone properties here. All properties of rocks are important as they define the type of rock and its application. Benmoreite belongs to Igneous Rocks while Soapstone belongs to Metamorphic Rocks.Texture of Benmoreite is Glassy, Massive, Porphyritic, Scoriaceous, Trachytic, Vesicular whereas that of Soapstone is Polished. Benmoreite appears Rough and Dull and Soapstone appears Dull, Banded and Foilated. The luster of Benmoreite is earthy while that of Soapstone is greasy. Benmoreite is available in black, brown, light to dark grey colors whereas Soapstone is available in black, black to grey, green, grey colors. The commercial uses of Benmoreite are commemorative tablets, creating artwork, curling 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).
