57Fe Mössbauer spectroscopy of banded iron formations from eastern India

Selected numbers of representative banded iron formations collected from various mines of iron ore supergroups were investigated using ore microscopy and Mossbauer spectroscopy. The ore microscopy results have been corroborated and compared with Mossbauer spectroscopy outcome. Different iron-bearing minerals present in these banded iron-formations have been quantified by 57Fe Mossbauer spectroscopy. The obtained results have been discussed on the basis of degree of martization and goethite-hematite abundance.
