Definition
Mangerite is a plutonic intrusive igneous rock, which is essentially a hypersthene-bearing monzonite
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

Archaeological Significance
Formation
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.
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

Mangerite vs Adakite 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. Mangerite vs Adakite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mangerite and Properties of Adakite. Learn more about Mangerite vs Adakite in the next section. The interior uses of Mangerite include Decorative aggregates and Interior decoration whereas the interior uses of Adakite include Decorative aggregates, Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Mangerite and Adakite, they have various applications in construction industry. The uses of Mangerite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate and that of Adakite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Mangerite and Adakite
Here you can know more about Mangerite and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mangerite and Adakite consists of mineral content and compound content. The mineral content of Mangerite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Mangerite vs Adakite, the texture, color and appearance plays an important role in determining the type of rock. Mangerite is available in black, brown, light to dark grey, white colors whereas, Adakite is available in black, brown, light to dark grey colors. Appearance of Mangerite is Shiny and that of Adakite is Dull and Soft. Properties of rock is another aspect for Mangerite vs Adakite. The hardness of Mangerite is 6-7 and that of Adakite is 3-4. The types of Mangerite are Plutonic rock whereas types of Adakite are Intermediate volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mangerite is white while that of Adakite is bluish black. The specific heat capacity of Mangerite is 0.92 kJ/Kg K and that of Adakite 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.Mangerite is heat resistant, impact resistant, pressure resistant whereas Adakite is heat resistant, pressure resistant, wear resistant.
