The voluminous 2.5 Ga banded iron formations (BIFs) from the Hamersley Basin (Australia) and Transvaal Craton (South Africa) record an extensive period of Fe redox cycling. The major Fe-bearing minerals in the Hamersley–Transvaal BIFs, magnetite and siderite, did not form in Fe isotope equilibrium, but instead reflect distinct formation pathways. The near-zero average dFe values for magnetite r...

This paper is devoted to determining whether the addition of geological information can improve resource estimate mineral resources. The geochemical data used come from 116 drill holes in Nkout East iron deposit southern Cameroon. These are modeled on Surpac and Isatis softwares represent 3D distribution deposit. Statistical analysis then a variographic study performed spatial variability iron....
