5 Formation

5.1 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.

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.

More about Tuff and Benmoreite

Here you can know more about Tuff and Benmoreite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Benmoreite consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite and mineral content of Benmoreite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase. You can also check out the list of all Igneous Rocks. When we have to compare Tuff vs Benmoreite, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Benmoreite is available in black, brown, light to dark grey colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Benmoreite is Rough and Dull. Properties of rock is another aspect for Tuff vs Benmoreite. The hardness of Tuff is 4-6 and that of Benmoreite is 6. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. whereas types of Benmoreite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB) and Tholeiitic Basalt. 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 Benmoreite is black. The specific heat capacity of Tuff is 0.20 kJ/Kg K and that of Benmoreite 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 Benmoreite is heat resistant, pressure resistant, wear resistant.
