The banded Iron-formation, corresponding mostly to oxide facies, exposed in the south-western parts of Chitradurga belt has been studied with respect to their field, petrographic, mineralogical and petrochemical aspects. It is concluded that, these iron-formations are essentially the results of chemical precipitation of iron and silica derived from continental weathering of basic rocks under anaerobic, quiet, below-wave base marine conditions. The banding is attributed to cyclic changes in climatic conditions.
