Modelling supergene mimetic martite goethite deposits

We recently applied a numerical modelling approach within the context of iron ore, to understand and quantify the major control of permeability anisotropy on supergene mimetic martite goethite deposits. The results are published in (Poulet et al., 2022). The figures above compare the mineralisation patterns between an observed cross-section (from Sommerville et al., 2014) with numerical results obtained from modelling anisotropic flow only.
