Definition
Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).
Mangerite is a plutonic intrusive igneous rock, which is essentially a hypersthene-bearing monzonite

Formation
Nephelinite 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.
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.

Nephelinite 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. Nephelinite vs Mangerite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Nephelinite and Properties of Mangerite. Learn more about Nephelinite vs Mangerite in the next section. The interior uses of Nephelinite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Mangerite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Nephelinite and Mangerite, they have various applications in construction industry. The uses of Nephelinite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate and that of Mangerite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.
More about Nephelinite and Mangerite
Here you can know more about Nephelinite and Mangerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Nephelinite and Mangerite consists of mineral content and compound content. The mineral content of Nephelinite includes Clinopyroxene, Nepheline, Plagioclase 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 Igneous Rocks. When we have to compare Nephelinite vs Mangerite, the texture, color and appearance plays an important role in determining the type of rock. Nephelinite is available in black, brown, colourless, green, grey, white colors whereas, Mangerite is available in black, brown, light to dark grey, white colors. Appearance of Nephelinite is Skeletal and that of Mangerite is Shiny. Properties of rock is another aspect for Nephelinite vs Mangerite. The hardness of Nephelinite is 6.5 and that of Mangerite is 6-7. The types of Nephelinite are Peralkaline Nephelinite whereas types of Mangerite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Nephelinite and Mangerite is white. The specific heat capacity of Nephelinite is 0.88 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.Nephelinite is heat resistant whereas Mangerite is heat resistant, impact resistant, pressure resistant.
