This map is part of a series which comprises 50 maps which covers the whole of Australia at a scale of 1:1 000 000 (1cm on a map represents 10km on the ground). Each standard map covers an area of 6 degrees longitude by 4 degrees latitude or about 590 kilometres east to west and about 440 kilometres from north to south. These maps depict natural and constructed features including transport infrastructure (roads, railway airports), hydrography, contours, hypsometric and bathymetric layers, localities and some administrative boundaries, making this a useful general reference map.

Indonesia is very prone to natural disasters, especially earthquakes, due to its location in a tectonically active region. In 2009, the 02 September 2009 Tasikmalaya and the 30 September 2009 earthquakes, with magnitude Mw 7.0 and 7.9, which are an intraslab earthquake, caused the deaths of thousands of people, severe infrastructure destruction and considerable economic loss. Then, the 02 October 2009 Kerinci earthquake, with magnitude Mw 6.6, is a crustal earthquake killed 3 people and destroyed hundreds of houses. Thus, both intraslab and crustal earthquakes are important sources of earthquake hazard in Indonesia.

The formation of iron oxide copper-gold (IOCG) deposits requires the conjunction in time and space of four essential components of the ore-forming mineral system: (1) energy source(s) to motivate the flow of hydrothermal fluids; (2) sources of ore components (metals, sulphur) and fluids; (3) favourable 'architecture' of permeable pathways for fluids, and (4) physico-chemical gradient sites for ore deposition. These components have been identified for IOCG systems in northern Queensland and South Australia, focussing on uranium-bearing IOCG deposits, during multidisciplinary studies of the energy potential of these regions. Each of the four system components was mapped using existing and newly acquired geological, geophysical and geochemical data. Using mineral potential modelling based on established approaches, maps of potential for uranium-bearing IOCG deposits (and for other uranium mineral systems) were created for each of the two regions. In north Queensland the under-cover extensions of the IOCG province hosted by the Mt Isa Eastern Succession were identified as highly prospective for IOCG deposits, although the potential for uranium-bearing systems appears to be more limited due to the relatively deep crustal levels of exposure. Potential for Paleozoic IOCG systems was also identified in the Etheridge Province. In South Australia the well known early Mesoproterozoic Olympic IOCG Province in the eastern Gawler Craton is proposed to extend westwards via the Mt Woods Inlier into the Coober Pedy Ridge region. A key result is the identification of IOCG potential in the northern Curnamona Province, of equivalent age and setting to that in the Gawler Craton

The Australian Solid Earth and Environment Grid (SEEGrid) is an eResearch infrastructure established to link diverse and distributed datasets in the geosciences, enable seamless interoperability between these, and undertake remote data processing. We present an integration between the GPlates plate-tectonic geographic information system and SEEGrid. Such a linkage is for the first time providing the necessary computational aids for abstracting an enormous level of complexity required for frontier solid-Earth research, in particular 4D metallogenesis. We present a continental reconstruction case study involving a proterozoic link between the greater Northern and Southern Australian cratons by combining evidence from several data sets. Faults are extracted from SEEGrid via Web Feature Services, and are used in conjunction with gravity anomaly data to test competing spatial alignment models of the reconstructed cratons. Additional information obtained from palaeomagnetic poles, granite geochemistry, geochronology, age-dated igneous provinces and other geophysics datasets can be used to further constrain the reconstruction. The metallogenic consequences of the best-fit reconstruction are profound, since they raises the possibility that the mineral systems hosting the giant Olympic dam, Broken Hill and Mt Isa could be linked in a particular geometry, resulting in a revised metallogenic map. The flexibility and extensibility of this spatio-temporal data analysis platform lends itself to a wide range of use-cases, including linking high-performance geodynamic modelling to kinematic reconstructions, creating the framework for future 3D and 4D metallogenic maps.

The Georgina Basin is a Neoproterozoic to Lower Devonian sedimentary basin covering 325,000 km2 of western Queensland and the Northern Territory. It is a northwest-southeast-trending extensional basin, with prospective conventional and unconventional hydrocarbon targets within Cambrian and Ordovician carbonate and siliciclastic rock units. The unconventional gas and oil potential of the basin has led to considerable recent exploration interest, although the basin has been relatively underexplored in the past. At the southern end of the basin, depocentres contain up to 2.2 km of Cambrian to Devonian sedimentary rocks, overlying Neoproterozoic sedimentary rocks over 1.5 km thick. The basin succession thins toward the north, where Cambrian sediments overlie the McArthur Basin sediments in the Beetaloo Sub-basin. Biostratigraphic interpretations of the prospective southern, central and eastern regions of the basin have been revised to reflect the 2012 Geological Time Scale (Gradstein et al. 2012), resulting in an updated chronostratigraphic framework for the basin. The revised biostratigraphic interpretations have implications for important hydrocarbon source rocks. For example, the limestone unit in the southern parts of the basin, generally regarded as the Thorntonia Limestone, is of a different age to the type section for this unit, located in the Undilla Sub-basin. Additionally, the basal 'hot shale' of the Arthur Creek Formation is diachronous across the Dulcie and Toko synclines, which may have ramifications for hydrocarbon exploration. This revised chronostratigraphic framework for the Georgina Basin provides a baseline for the first basin-wide assessment of the unconventional hydrocarbon potential of the basin, by Geoscience Australia.
