“…Oxide-Apatite (Dupuis and Beaudoin, 2011), VMS deposits (Singoyi et al, 2006;Makvandi et al, 2016), carbonatite in Phalaborwa (Milani et al, 2016), as well as porphyry Cu-Mo, skarn, Ag-Pb-Zn veins, and BIF (Dupuis and Beaudoin, 2011;Nadoll, 2011;Nadoll et al, 2014). Recently, magnetite and hematite compositions have been used to identify the involvement of metamorphic and hydrothermal fluids in the genesis of high-grade iron orebodies hosted by BIF in the Quadrilátero Ferrífero, Brazil (Cabral and Rosière, 2013;Hensler et al, 2015), and the Koolyanobbing and Marda greenstone belts, Western Australia (Angerer et al, 2012;Angerer et al, 2013). Divalent cations such as Mg, Ni, Mn, Co, and Zn may substitute for Fe 2+ sites in magnetite; trivalent cations such as Al, Cr, V, Mn, and Ga replace Fe 3+ sites in magnetite or hematite (Lindsley,1λ76;Wechsler et al,1λ84), whereas cations with higher valencies (e.g.…”

“…In contrast, relatively juvenile regions represent more active, unstable environments where more continuous, rapid emplacement of komatiites and basalts, as well as associated hydrothermal systems, led to thinner BIF sequences (Lascelles 2007). This spatial variation can be observed in the different stratigraphy of the Marda (thick BIFs, basaltic volcanism) and Forrestania (thin BIFs and abundant komatiites) greenstone belts (Chen et al 2003;Angerer & Hagemann 2010;Angerer et al 2012a).…”

“…Iron camps (e.g. Weld Range, Windarling) form along major structures orientated parallel to isotopic margins (Angerer et al 2012a;Duuring & Hagemann 2013a, b), suggesting an intimate regional relationship between major crustal boundaries and these localizing faults (Fig. 12).…”

“…However, when it comes to precious metal 54 remobilisation under mid-crustal conditions the process is controversial due to the inferred low 55 solubilities of these elements in aqueous fluids, the extremely slow rates of element diffusion in 56 minerals and poor understanding of how metals are soluble in one location but re-precipitated just a 57 short distance away. Despite these arguments, there is a common spatial relationship between primary 58 sulphides containing trace metals in their crystal structure, and nearby, texturally younger 59 concentrations of those metals, often at very high grades (Cook et Metal migration has been documented in volcanic massive sulphides (VMS) systems (Cook et al, 62 1998;Cook, 1996;Le Vaillant et al, 2015;Marshall and Gilligan, 1993;Tomkins, 2007), iron ore 63 systems (Angerer et al, 2013;Duuring and Hagemann, 2013) and also in gold systems (Cook et Ni sulphide deposit (Le Vaillant et al, 2015), the significant upgrade of hypogene ores at the Beebyn 68 iron deposit (Duuring and Hagemann, 2013) and spectacular native gold occurrences in the Red Lake 69 gold deposit (Dubé et al, 2004). 70…”
