“…We also assess the depositional context of the BIFs within their host-rocks. In detail, the purpose of this paper is two-fold: (1) Document the BIF's geochemical datasets; and (2) define the BIF's depositional settings at a regional scale, in a relatively poorly documented area when compared to the analogous, well documented BIFs from Cameroon [10][11][12][13][14][15][16][17][18] or Gabon [19].…”

Depositional Setting of Archean BIFs from Congo: New Insight into Under-Investigated Occurrences

Archean banded iron formations (BIF) represent a major contributor to better constraining and assessing the paleogeography and evolution of Archean cratons. In this context, we conducted an exhaustive sampling and analysis campaign of BIF units in the Congo Craton, covering several greenstone belts within the Ivindo, Kelle-Mbomo, and Chaillu blocks. The REE + Y patterns suggest: (1) Interaction of seawater with Fe-oxyhydroxides, as illustrated by strong REE enrichment coupled with La and Y enrichment; (2) contributions from high-temperature (>250 °C) hydrothermal fluids, illustrated by positive Eu anomalies; and (3) detrital input as suggested by relatively consistent REE concentrations and a chondritic Y/Ho ratio. These observations suggest a typical environment of Algoma-type BIF deposition. Moreover, assessment of the Ce anomalies in a combination of HREE enrichment indicates that some basins in the Chaillu and Ivindo blocks may have known potential oxygen-rich episodes in the early Archean during the deposition of these BIFs.

“…The hematite-rich deposits are located in Mbalam and Nkout, while the magnetite-rich deposits are found in various sites such as Elom, Zambi, Kouambo, Bikoula, Kpwa-Atog Boga and Meyomessi (Fig. 1) (Soh Tamehe et al, 2019). The Ntem Complex BIFs were deposited on a passive margin, similar to that of Superior-type (Ganno et al, 2016(Ganno et al, , 2017Soh Tamehe et al, 2018), except for the Bikoula and Kelle-Bidjoka BIFs, which are closer to the Algoma-type (Teutsong et al, 2017;Nzepang Tankwa et al, 2021).…”

In the Republic of Congo, Banded iron formations (BIFs) occur in two areas: the Chaillu Massif and the Ivindo Basement Complex, which are segments of the Archean Congo craton outcropping in the northwestern and southwestern parts of the country. They show interesting potential with significant mineral resources reaching 2 Bt and grades up to 60% Fe. BIFs consist mostly of oxide-rich facies (hematite/magnetite), but carbonate-rich facies are also highlighted. They are found across the country within the similar geological sequences composed of amphibolites, gneisses and greenschists. The Post-Archean Australian Shale (PAAS)-normalized patterns of BIFs show enrichment in elements such as SiO

“…Iron ore can be found in a variety of geological formations, and characterizing them is crucial for figuring out how they are formed and how much iron they contain. Mineralogy is a crucial stage in the design and expansion of iron ore mining [ 1 , 10 , 11 ]. Iron ore is being mined in the main parts of the world, but still, the high cost of steel is experienced [ 12 ].…”
