Iron oxide copper gold (IOCG) deposits are considered to be metasomatic expressions of large crustalscale alteration events driven by intrusive activity. The deposit type was first recognised, though not named as IOCG, by discovery and study of the supergiant Olympic Dam coppergolduranium deposit (Olympic Dam mine), and South American examples.

Many diverse ore systems are classified together as iron oxide coppergold (lOCG) deposits based on an empirical definition arising primarily from geochemical features that do not specify tectonic setting, geologic environment, or sources of oreforming fluid, metals, or other ore components. Such deposits have (1) Cu, with or without Au, as economic metals; (2) hydrothermal ore styles and ...

The rich coppergold ore bodies at Tennant Creek are genetically related to BHP''s giant Olympic Dam, or iron oxide copper gold deposit in South Australia. However, whilst the Tennant Creek deposits haven''t yet matched Olympic Dam in terms of overall size, they certainly make up for it in grade.
May 01, 2020· Previous studies at Productora concluded the deposit had strong affinities with the iron oxide coppergold (IOCG) clan and likened the deposit to Candelaria. Based on new information, we document the deposit geology in detail and propose a new genetic model and alternative classification as a magmatichydrothermal breccia complex with closer ...

The brecciosted Ernest Henry deposit differs from the generally hematiterich IOCG deposits in the Olympic IOCG Province in that the major iron oxide is magnetite, with associated hydrothermal Kfeldspar, biotite and carbonate (Williams et al., 2005).
to distinguish this group from sedimentary iron deposits, magmatic iron–titanium oxide deposits, and other iron oxidebearing hydrothermal deposits, such as many members of the porphyry copper clan (Chapter ). In particular, this usage does not restrict IOCG to those deposits containing economic concentrations of copper and(or) gold (cf ...
