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