Definition

Definition

Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks
Monzonite is a granular igneous rock with composition between syenite and diorite and containing approximately equal amounts of orthoclase and plagioclase

Formation

Formation

Gneiss is a high grade metamorphic rock i.e. it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of Gneiss forms from volcanic rock, shale or granitie.
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.

Gneiss vs Monzonite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Gneiss and Monzonite Reserves. Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. Monzonite is a granular igneous rock with composition between syenite and diorite and containing approximately equal amounts of orthoclase and plagioclase. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Gneiss vs Monzonite information and Gneiss vs Monzonite characteristics in the upcoming sections.

Gneiss 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. Gneiss vs Monzonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gneiss and Properties of Monzonite. Learn more about Gneiss vs Monzonite in the next section. The interior uses of Gneiss include Countertops, Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Monzonite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Gneiss and Monzonite, they have various applications in construction industry. The uses of Gneiss in construction industry include As dimension stone and that of Monzonite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.

More about Gneiss and Monzonite

Here you can know more about Gneiss and Monzonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gneiss and Monzonite consists of mineral content and compound content. The mineral content of Gneiss includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon 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 Gneiss vs Monzonite, the texture, color and appearance plays an important role in determining the type of rock. Gneiss is available in black, brown, pink, red, white colors whereas, Monzonite is available in black, brown, light to dark grey, white colors. Appearance of Gneiss is Foliated and that of Monzonite is Shiny. Properties of rock is another aspect for Gneiss vs Monzonite. The hardness of Gneiss is 7 and that of Monzonite is 6-7. The types of Gneiss are Augen Gneiss, Henderson Gneiss, Lewisian Gneiss, Archean and Proterozoic Gneiss. 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 Gneiss and Monzonite is white. The specific heat capacity of Gneiss is 0.70 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.Gneiss is heat resistant, pressure resistant, scratch resistant, wear resistant whereas Monzonite is heat resistant, impact resistant, pressure resistant.
