Definition
Banded iron formation are distinctive units of sedimentary rock that are almost always of Precambrian age
  
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
  
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
