Abstract

Deep crustal seismic data collected in 2006 and 2007 highlight prospectivity for geothermal and energy mineral systems in north Queensland as well as providing insight into geodynamic controls on IOCG(U) and metasomatic U deposits. IOCG deposits in the eastern Mt Isa Inlier are located in the hanging wall of a major crustal discontinuity that is imaged at surface as a gravity high. At a broader scale these deposits are spatially associated with the Carpentaria conductance anomaly, which can be traced south to the Olympic IOCG(U) deposit. The surveys also identified the previously unknown Millungera Basin which appears to overlie granitic bodies. This architecture is favourable for the presence of geothermal systems, with the granites providing heat beneath the basin insulator and heat trap. This basin has unknown potential for petroleum and energy minerals. Metasomatic deposits in the western Mt Isa Inlier appear to be associated with inverted extensional faults that bound major troughs. Inversion of these faults during the Isan Orogeny allowed fluid flow to suitable U traps.
