5 Formation

5.1 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.

Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.

More about Soapstone and Tuff

Here you can know more about Soapstone and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Tuff consists of mineral content and compound content. The mineral content of Soapstone includes Albite, Apatite, Biotite, Calcite, Carbonate, Clay Minerals, Hornblende, Ilmenite, Micas, Plagioclase, Pyroxene, Quartz and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Metamorphic Rocks. When we have to compare Soapstone vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Soapstone is available in black, black to grey, green, grey colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Soapstone is Dull, Banded and Foilated and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Soapstone vs Tuff. The hardness of Soapstone is 1 and that of Tuff is 4-6. The types of Soapstone are Not Available whereas types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Soapstone is black while that of Tuff is white. The specific heat capacity of Soapstone is 0.88 kJ/Kg K and that of Tuff is 0.20 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Soapstone is heat resistant, pressure resistant whereas Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
