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.
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

The uses of Mangerite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate and that of Shonkinite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Mangerite and Shonkinite
Here you can know more about Mangerite and Shonkinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mangerite and Shonkinite 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 Shonkinite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Mangerite vs Shonkinite, 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, Shonkinite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Mangerite is Shiny and that of Shonkinite is Banded and Foilated. Properties of rock is another aspect for Mangerite vs Shonkinite. The hardness of Mangerite is 6-7 and that of Shonkinite is 5.5-6. The types of Mangerite are Plutonic rock whereas types of Shonkinite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mangerite and Shonkinite is white. The specific heat capacity of Mangerite is 0.92 kJ/Kg K and that of Shonkinite 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.Mangerite is heat resistant, impact resistant, pressure resistant whereas Shonkinite is heat resistant, impact resistant, wear resistant.
