Iron Ore Deposit of Orissa-Jharkhand Region (With Map) India
ADVERTISEMENTS: The Iron Ore Super-group-bearing northern Orissa is separated from Talchir Gondwana rocks and Eastern Ghat Super-group by Sukinda Thrust zone (northern fault of Gondwana basin). The iron ore district of Orissa-Jharkhand is, thus, confined to the Singhbhum-Sukinda thrust belts in the north and south (Figure 5.1).Banded iron-formations (BIFs) are marine chemical sedimentary rocks composed of siliceous and ferric materials, usually with typical thin layers or sheet structures. BIFs not only record a wealth of information about the state and evolution of the lithosphere, atmosphere, hydrosphere, and biosphere but also host the majority of the Origin of Banded Iron Formations: Links with Paleoclimate

They are Bonai-KeonjharSequence stratigraphy can be used as a generic, process-based method for mapping and correlation within a sedimentary basin that is independent of the geological setting and data used. Where sections of the BIF have been enriched through supergene or hypergene processes, they form high-grade iron ore deposits (Mloszewska et al. 2015Stratigraphic Sequence SpringerLink

In China, the BIF-related iron deposits are the most important type of iron deposits, accounting for approximately 64% of the total identified resources. However, most of them are low-grade iron ores (in China, the low-grade iron ore is defined as 20% ≤ TFe < 50%, and the iron Types and general characteristics of the BIF-related iron deposits

Offshore sediments record the history of onshore iron ore
As the demand for Mn ore diminished, the mining sites shifted from south Goa to iron ore deposits of north Goa (Bicholim taluka) (Panchang et al., 2005 and the references therein). The reason for the very sharp rise in linear sedimentation rate (0.19 to 1.57 cm/yr) at 1982 may be due to this shifting of mining sites to the catchment area of
