Suevite and Banded iron formation
Definition
Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Banded iron formation are distinctive units of sedimentary rock that are almost always of Precambrian age

Formation
Formation
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.
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 Suevite and Banded iron formation Properties
Know all about Suevite and Banded iron formation properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Banded iron formation belongs to Sedimentary Rocks.Texture of Suevite is Earthy whereas that of Banded iron formation is Banded, Trellis. Suevite appears Banded and Banded iron formation appears Layered, Banded, Veined and Shiny. The luster of Suevite and Banded iron formation is earthy. Suevite 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 Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Banded iron formation are as a touchstone, cemetery markers, creating artwork.
