Department of Natural Resources and Mines Geological Survey of Queensland North-West Queensland Mineral and Energy Province Report and Data Package JXOy 2014 The North-West Queensland Mineral and Energy Province Report with accompanying data package is the culmination of five years field and officebased study of the North West Queensland Mineral and Energy Province (NWQMEP) by the Geological Survey of Queensland. The work was funded by the Queensland Government’s Smart Exploration and Smart Mining initiatives. The NWQMEP is Australia’s largest copper, lead, zinc and silver producer. The region hosts almost 30 per cent of the world’s lead–zinc reserves and continues to produce new world-class discoveries such as the Merlin Cu-Au-Mo-Re deposit. The region also has significant energy potential, including non-traditional sources such as geothermal and shale gas. Since the last major synthesis of this region by the Department of Mines and Energy and others in 2000 (North-West Queensland Mineral Province Study), significant new research has been undertaken in this and other equivalent Australian Proterozoic sequences. Major technological advances have improved the processing, integration, visualisation and analysis of geoscientific data. The goal of this study was to enhance the effectiveness of exploration in this region by consolidating existing information. In addition to new mapping and isotopic dating, new technologies and work processes have been applied to give fresh insights into the evolution, 3D architecture and controls on the distribution of mineral and energy resources. The results are presented in this hard copy report and data package set—complete with accompanying time–space diagrams, a solid geology map and two DL DVDs containing 14 appendixes that include a GIS, 3D models, exploration geochemistry database, bibliography and various detailed reports as pdf documents. Content and format • An overview of the characteristics of the Proterozoic geological domains —a new subdivision of the province has been produced which reflects combinations of basin evolution, structural grain, metamorphic grade and geochronology and provides a flexible framework for describing variations in the geology and deformational responses between different parts of the region. • A synthesis of the Proterozoic geodynamic evolution of the Mount Isa Inlier —based on 11 time-slices and providing a uniform geodynamic interpretation of the major deformation events and their effects. • A model of the Proterozoic tectonic evolution of the Mount Isa Inlier from an Australia-wide perspective. • Two time–space plots outlining the chrono-stratigraphy and tectonic events at two levels of detail —the Mount Isa Inlier and the entire Proterozoic of eastern Australia. The Mount Isa time–space plot includes results from new isotopic dating of igneous rocks and sedimentary successions, stratigraphic relationships, timing of mineralisation, and an overview of the major tectonic events. Great state. Great opportunity. • Surface and solid geology as a seamless dataset —integrates new geological mapping of outcropping areas and extends this under Phanerozoic cover based on interpretation of potential field, drill-hole and deep crustal seismic datasets. • A 3D model covering the entire NWQMEP study area —model displays the spatial associations of geological features at depth and beneath cover, to provide a conceptual framework for more specific studies of basin evolution, deformation, fluid flow and mineral systems. It also includes geophysically modelled regions of the deep crust and a new depth-to-basement surface. • Mineral systems analysis —of structurally controlled epigenetic Iron Oxide-Cu-Au (IOCG) deposits and Ag-Pb-Zn in high-grade metamorphic terranes in the east and stratabound sediment-hosted Zn-Pb-Ag and structurally-controlled epigenetic Cu±Au deposits in the west of the region. • Exploration geochemistry and drill hole database —comprises over 1.3 million attributed data points from stream sediment, rock chip, soil and drill hole sampling. • Attributed GIS dataset in ArcGIS and MapInfo formats —includes the following layers: • detailed surface and solid geology as arcs and polygons and various derived layers including an attributed fault array • infrastructure and administrative areas • mineral occurrences • geophysical and Landsat images • depth-to-basement interpretation • topography and digital elevation data —ArcReader software and an ArcGIS ECW plugin are provided to allow users without ArcGIS or MapInfo software to view the data. • Bibliography —in a MS Access database and an EndNote library, including publications from government, academic and industry geoscientists and providing comprehensive coverage of most aspects of the geology and evolution of the province. Further information • A geothermal prospectivity assessment of the Phanerozoic successions —including the Carpentaria, Eromanga, Galilee, Georgina and Millungera Basins, delineating areas with potential for hot sedimentary aquifers and enhanced geothermal systems. • Synthesis of current knowledge of carbon-based energy resources —in Phanerozoic strata overlying and surrounding the Mount Isa Inlier. This has been sourced from petroleum, water and government stratigraphic drilling, surface geological mapping and previously published reviews of the basins. The price of the complete report and data package is $317.70 (including GST), DVD only $131.90, plus postage and handling.
