Formation
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.
Pantellerite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Tuff and Pantellerite
Here you can know more about Tuff and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Pantellerite consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite and mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Tuff vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Tuff vs Pantellerite. The hardness of Tuff is 4-6 and that of Pantellerite is 6-7. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. whereas types of Pantellerite are Pantelleritic Ignimbrite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tuff is white while that of Pantellerite is . The specific heat capacity of Tuff is 0.20 kJ/Kg K and that of Pantellerite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Tuff is heat resistant, impact resistant, pressure resistant, wear resistant whereas Pantellerite is heat resistant.
