Introduction. Iron oxide copper–gold (IOCG) provinces consist of a set of contemporaneous, structurally-controlled deposits, in which vertical, crustal-scale structures form the pathways for fluid circulation towards intermediate to epizonal levels, where most parts of the known IOCG deposits are interpreted to form (Hitzman et al., 1992, Williams …

The role of lithospheric architecture and the mantle in the genesis of iron oxide copper-gold (IOCG) deposits is controversial. Using the example of the Precambrian Gawler Craton (South Australia), which hosts the giant Olympic Dam IOCG deposit, we integrate geophysical data (seismic tomography and magnetotellurics) with geological …
