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.
The banded iron layers are formed in sea water when oxygen is released by photosynthetic cyano-bacteria. The oxygen then combines with dissolved iron in ocean to form insoluble iron oxides, which precipitated out, forming a thin layer of banded iron formation on ocean floor.

More about Mangerite and Banded iron formation
Here you can know more about Mangerite and Banded iron formation. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mangerite and Banded iron formation 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 Banded iron formation includes Hematite, Magnetite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Mangerite vs Banded iron formation, 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, Banded iron formation is available in red, reddish brown colors. Appearance of Mangerite is Shiny and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Mangerite vs Banded iron formation. The hardness of Mangerite is 6-7 and that of Banded iron formation is 5.5-6. The types of Mangerite are Plutonic rock whereas types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mangerite and Banded iron formation is white. The specific heat capacity of Mangerite is 0.92 kJ/Kg K and that of Banded iron formation is 3.20 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 Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant.
