Definition
Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin
Monzonite is a granular igneous rock with composition between syenite and diorite and containing approximately equal amounts of orthoclase and plagioclase

Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

Skarn 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. Skarn vs Monzonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Skarn and Properties of Monzonite. Learn more about Skarn vs Monzonite in the next section. The interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Monzonite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Skarn and Monzonite, they have various applications in construction industry. The uses of Skarn in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Gold and silver production, Manufacture of magnesium and dolomite refractories and that of Monzonite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.
More about Skarn and Monzonite
Here you can know more about Skarn and Monzonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Monzonite consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite 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 Metamorphic Rocks. When we have to compare Skarn vs Monzonite, the texture, color and appearance plays an important role in determining the type of rock. Skarn is available in black, brown, green, grey, white colors whereas, Monzonite is available in black, brown, light to dark grey, white colors. Appearance of Skarn is Dull and that of Monzonite is Shiny. Properties of rock is another aspect for Skarn vs Monzonite. The hardness of Skarn is 6.5 and that of Monzonite is 6-7. The types of Skarn are Endoskarns 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 Skarn is light to dark brown while that of Monzonite is white. The specific heat capacity of Skarn is 0.92 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.Skarn is heat resistant whereas Monzonite is heat resistant, impact resistant, pressure resistant.
