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
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.
