Genesis of Iron Ores from Precambrian Banded Iron Formation in the Archean Badampahar Greenstone Belt, Iron Ore Group, East Indian Shield
Journal Title: Journal of Advanced Research in Geo Sciences & Remote Sensing - Year 2018, Vol 5, Issue 3
Abstract
Banded Iron Formations (BIFs), as the name suggests, are chemically precipitated sedimentary rocks having alternating Fe-rich and Si-rich bands. The origin of BIF has always remained a debated topic of research. The BIF in the Badampahar Greenstone Belt is of Mesoarchean age that formed a part of the East Indian Shield. Here, the BIF is interlayered with metavolcanic rocks, quartzite, phyllite, and chert, which indicates a typical greenstone sequence. The present paper focuses a little on the depositional setting of the BIF and mostly on the post-depositional processes, which include formation of iron ores. Geochemical and sedimentological evidences suggest insignificant detrital input in the genesis of BIF and significant chemical precipitation in the deposition. The post-depositional processes involved subsequent stages of deformation, metamorphism, hydrothermal, and supergene processes after deposition. Hydrothermal fluid is found enriched in High Field Strength Elements (HFSEs) and transition elements. This hydrothermal fluid altered the BIF to form titanomagnetite and ilmenite-rich rock in Jashipur. Recycling of BIF magnetite into hematite and removal of silica also attributed to hydrothermal alteration, which ultimately led to form iron ores.
