Formation

Formation

Foidolites 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 Foidolite and Banded iron formation

Here you can know more about Foidolite 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 Foidolite and Banded iron formation consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene 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 Foidolite vs Banded iron formation, the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, green, grey, pink, white colors whereas, Banded iron formation is available in red, reddish brown colors. Appearance of Foidolite is Dull and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Foidolite vs Banded iron formation. The hardness of Foidolite is 1.5 and that of Banded iron formation is 5.5-6. The types of Foidolite are Igneous 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 Foidolite and Banded iron formation is white. The specific heat capacity of Foidolite is 0.79 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.Foidolite is heat resistant, wear resistant whereas Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant.
