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
Mangerite is a plutonic intrusive igneous rock, which is essentially a hypersthene-bearing monzonite

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.
Mangerite 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 Mangerite 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 Mangerite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gneiss and Properties of Mangerite. Learn more about Gneiss vs Mangerite in the next section. The interior uses of Gneiss include Countertops, Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Mangerite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Gneiss and Mangerite, they have various applications in construction industry. The uses of Gneiss in construction industry include As dimension stone and that of Mangerite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.
More about Gneiss and Mangerite
Here you can know more about Gneiss and Mangerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gneiss and Mangerite 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 Mangerite 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 Mangerite, 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, Mangerite is available in black, brown, light to dark grey, white colors. Appearance of Gneiss is Foliated and that of Mangerite is Shiny. Properties of rock is another aspect for Gneiss vs Mangerite. The hardness of Gneiss is 7 and that of Mangerite is 6-7. The types of Gneiss are Augen Gneiss, Henderson Gneiss, Lewisian Gneiss, Archean and Proterozoic Gneiss. whereas types of Mangerite are Plutonic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gneiss and Mangerite is white. The specific heat capacity of Gneiss is 0.70 kJ/Kg K and that of Mangerite 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 Mangerite is heat resistant, impact resistant, pressure resistant.
