Formation

Sovites are formed due to low degrees of partial melting of 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.

All about Sovite and Banded iron formation Properties

Know all about Sovite and Banded iron formation properties here. All properties of rocks are important as they define the type of rock and its application. Sovite belongs to Igneous Rocks while Banded iron formation belongs to Sedimentary Rocks.Texture of Sovite is Granular, Poikiloblastic whereas that of Banded iron formation is Banded, Trellis. Sovite appears Dull, Banded and Foilated and Banded iron formation appears Layered, Banded, Veined and Shiny. The luster of Sovite is subvitreous to dull while that of Banded iron formation is earthy. Sovite is available in black, brown, green, grey, pink, white colors whereas Banded iron formation is available in red, reddish brown colors. The commercial uses of Sovite are an oil and gas reservoir, as a feed additive for livestock, creating artwork, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) and that of Banded iron formation are as a touchstone, cemetery markers, creating artwork.
