Formation
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.
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.

All about Turbidite and Banded iron formation Properties
Know all about Turbidite and Banded iron formation properties here. All properties of rocks are important as they define the type of rock and its application. Turbidite and Banded iron formation belong to Sedimentary Rocks.Texture of Turbidite is Mud-rich, Sandy whereas that of Banded iron formation is Banded, Trellis. Turbidite appears Dull and Banded and Banded iron formation appears Layered, Banded, Veined and Shiny. The luster of Turbidite is metallic while that of Banded iron formation is earthy. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas Banded iron formation is available in red, reddish brown colors. The commercial uses of Turbidite are cemetery markers, creating artwork and that of Banded iron formation are as a touchstone, cemetery markers, creating artwork.
