Formation
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Banded iron formation and Jadeitite
Here you can know more about Banded iron formation and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Banded iron formation and Jadeitite consists of mineral content and compound content. The mineral content of Banded iron formation includes Hematite, Magnetite, Quartz and mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Banded iron formation vs Jadeitite, the texture, color and appearance plays an important role in determining the type of rock. Banded iron formation is available in red, reddish brown colors whereas, Jadeitite is available in black, brown, colourless, green, grey, white colors. Appearance of Banded iron formation is Layered, Banded, Veined and Shiny and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Banded iron formation vs Jadeitite. The hardness of Banded iron formation is 5.5-6 and that of Jadeitite is 3-5. The types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite whereas types of Jadeitite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Banded iron formation is white while that of Jadeitite is white, greenish white or grey. The specific heat capacity of Banded iron formation is 3.20 kJ/Kg K and that of Jadeitite is 0.95 kJ/Kg K.
