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.
Monzonite 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 vs Monzonite 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. Tuff vs Monzonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tuff and Properties of Monzonite. Learn more about Tuff vs Monzonite in the next section. The interior uses of Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Monzonite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Tuff and Monzonite, they have various applications in construction industry. The uses of Tuff in construction industry include Building houses or walls, Construction aggregate and that of Monzonite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.
More about Tuff and Monzonite
Here you can know more about Tuff and Monzonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Monzonite consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite and mineral content of Monzonite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Tuff vs Monzonite, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Monzonite is available in black, brown, light to dark grey, white colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Monzonite is Shiny. Properties of rock is another aspect for Tuff vs Monzonite. The hardness of Tuff is 4-6 and that of Monzonite is 6-7. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. whereas types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tuff and Monzonite is white. The specific heat capacity of Tuff is 0.20 kJ/Kg K and that of Monzonite is 0.92 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 Monzonite is heat resistant, impact resistant, pressure resistant.
