Geological Controls on HighGrade Iron Ores from Kiriburu

Numerous iron ore deposits are hosted within the Meso to Neo-Archean banded iron formations BIFs extending across the Singhbhum-Orissa Craton, eastern India. Despite the widespread distribution of BIFs, which forms part of the iron ore group IOG, heterogeneity in their grade and mineral composition is occasionally observed even within a single ore deposit.
