Abstract

The banded iron formation (BIF), corresponding mostly to oxide facies, exposed in north eastern parts of the Sandur greenstone belt has been studied with respect to their field, Petro graphic, 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, quiest, below-wave base marine conditions. The banding is attributed to cyclic changes in climatic conditions.
