Archaeological Significance
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.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

Monzonite vs Scoria 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 Scoria characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Monzonite and Properties of Scoria. Learn more about Monzonite vs Scoria in the next section. The interior uses of Monzonite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Scoria include Decorative aggregates and Interior decoration. Due to some exceptional properties of Monzonite and Scoria, 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 Scoria include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works.
More about Monzonite and Scoria
Here you can know more about Monzonite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzonite and Scoria 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 Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Monzonite vs Scoria, 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, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Monzonite is Shiny and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Monzonite vs Scoria. The hardness of Monzonite is 6-7 and that of Scoria is 5-6. The types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite whereas types of Scoria are Basaltic Scoria and Andesitic Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Monzonite and Scoria is white. The specific heat capacity of Monzonite is 0.92 kJ/Kg K and that of Scoria 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.Monzonite is heat resistant, impact resistant, pressure resistant whereas Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
