Formation
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.
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 vs Tuff Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Pantellerite vs Tuff characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pantellerite and Properties of Tuff. Learn more about Pantellerite vs Tuff in the next section. The interior uses of Pantellerite include Not yet used whereas the interior uses of Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Pantellerite and Tuff, they have various applications in construction industry. The uses of Pantellerite in construction industry include Na and that of Tuff include Building houses or walls, Construction aggregate.
More about Pantellerite and Tuff
Here you can know more about Pantellerite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Tuff consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all . When we have to compare Pantellerite vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Pantellerite is Layered and Foliated and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Pantellerite vs Tuff. The hardness of Pantellerite is 6-7 and that of Tuff is 4-6. The types of Pantellerite are Pantelleritic Ignimbrite 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 Pantellerite is unknown while that of Tuff is white. The specific heat capacity of Pantellerite is Not Available 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.Pantellerite is heat resistant whereas Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
