Formation
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
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 Whiteschist and Banded iron formation
Here you can know more about Whiteschist 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 Whiteschist and Banded iron formation consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Banded iron formation includes Hematite, Magnetite, Quartz. You can also check out the list of all . When we have to compare Whiteschist vs Banded iron formation, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in colourless, green, grey, white colors whereas, Banded iron formation is available in red, reddish brown colors. Appearance of Whiteschist is Banded and Foilated and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Whiteschist vs Banded iron formation. The hardness of Whiteschist is 1.5 and that of Banded iron formation is 5.5-6. The types of Whiteschist are Not Available 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 Whiteschist and Banded iron formation is white. The specific heat capacity of Whiteschist 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.Whiteschist is heat resistant whereas Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant.
