CC BY 4.0 License. 1 Basin inversion and structural architecture as constraints on fluid 2 flow and Pb-Zn mineralisation in the Paleo-Mesoproterozoic 3 sedimentary sequences of northern Australia 4 5 George M. Gibson, Research School of Earth Sciences, Australian National University, Canberra ACT 6 2601, Australia 7 Sally Edwards, Geological Survey of Queensland, Department of Natural Resources, Mines and Energy, 8 Brisbane, Queensland 4000, Australia 9 Abstract 10 As host to several world-class sediment-hosted Pb-Zn deposits and unknown quantities of conventional and 11 unconventional gas, the variably inverted 1730-1640 Ma Calvert and 1640-1580 Ma Isa superbasins of 12 northern Australia have been the subject of numerous seismic reflection studies with a view to better 13 understanding basin architecture and fluid migration pathways. Strikingly similar structural architecture 14 has been reported from much younger inverted sedimentary basins considered prospective for oil and gas 15 elsewhere in the world. Such similarities suggest that the mineral and petroleum systems in Paleo- 16 Mesoproterozoic northern Australia may have spatially and temporally overlapped consistent with the 17 observation that basinal sequences hosting Pb-Zn mineralisation in northern Australia are bituminous or 18 abnormally enriched in hydrocarbons. This points to the possibility of a common tectonic driver and shared 19 fluid pathways. Sediment-hosted Pb-Zn mineralisation coeval with basin inversion first occurred during the 20 1650-1640 Ma Riversleigh Tectonic Event towards the close of the Calvert Superbasin with further pulses 21 accompanying the 1620-1580 Ma Isa Orogeny which brought about closure of the Isa Superbasin. -

State Coastal Management Plan
Schedule 1: Regional overviews The Queensland coast has been subdivided into eleven coastal regions for the purpose of preparing regional coastal plans. The regions’ boundaries are based on coastal local government boundaries. The overview for each region generally describes the region, its coastal resources, existing management and administration arrangements, and the key coastal management issues.18 The eleven coastal regions are illustrated in map 1. Map 3 shows the terrestrial and marine bioregions referred to in this schedule.

Mount Isa Inlier Bioregion
Mount Isa Inlier bioregion Description Figure 2 Monitoring data coverage Area: 66 640 km2 NT The landforms of the Mount Isa Inlier bioregion include rugged hills and mountain ranges separated by undulating valleys. The predominant vegetation is low open woodland over spinifex hummock grassland. The major land use is cattle grazing on pastoral leases. Mining (copper and lead-zinc) is very important to QLD the bioregion’s economy, and tourism is expanding. Major population centres are Mount Isa and Cloncurry. Location The Mt Isa Inlier bioregion is located in western bioregion boundary AussieGRASS data Queensland with a very small portion (0.3%) extending into the Northern Territory (NT; see Monitoring data coverage Figures 1 and 2). Data sources available Figure 1 Location of the Mount Isa Data sources include: Inlier bioregion n AussieGRASS simulation (of pasture growth and utilisation) and remote sensing (Multiple Regression Bare Ground Index, version bi1); these data sources provide low to moderate reliability for reporting change (entire rangelands, simulated results with some ground validation rather than direct measurement or observation) n domestic stocking density, which provides moderate reliability n fire extent, intensity and frequency, which provides high reliability n dust n distance from water Location of Mount Isa Inlier bioregion n distribution and relative abundance of invasive animals and weeds n land use n land values. Mount Isa Inlier bioregion 1 Climate Utilisation was close to the safe threshold for the Thorntonia sub-IBRA. The Mount Isa Inlier bioregion has a hot and semiarid climate with summer-dominant rainfall. Utilisation decreased by 4% (absolute, and 19% in Spatially averaged median (1890–2005) rainfall is relative terms) for the Southwestern Plateaus 388 mm (April to March rainfall year; see Figure 3). -
Queensland Geological Framework
Geological framework (Compiled by I.W. Withnall & L.C. Cranfield) The geological framework outlined here provides a basic overview of the geology of Queensland and draws particularly on work completed by Geoscience Australia and the Geological Survey of Queensland. Queensland contains mineralisation in rocks as old as Proterozoic (~1880Ma) and in Holocene sediments, with world-class mineral deposits as diverse as Proterozoic sediment-hosted base metals and Holocene age dune silica sand. Potential exists for significant mineral discoveries in a range of deposit styles, particularly from exploration under Mesozoic age shallow sedimentary cover fringing prospective older terranes. The geology of Queensland is divided into three main structural divisions: the Proterozoic North Australian Craton in the north-west and north, the Paleozoic–Mesozoic Tasman Orogen (including the intracratonic Permian to Triassic Bowen and Galilee Basins) in the east, and overlapping Mesozoic rocks of the Great Australian Basin (Figure 1). The structural framework of Queensland has recently been revised in conjunction with production of a new 1:2 million-scale geological map of Queensland (Geological Survey of Queensland, 2012), and also the volume on the geology of Queensland (Withnall & others, 2013). In some cases the divisions have been renamed. Because updating of records in the Mineral Occurrence database—and therefore the data sheets that accompany this product—has not been completed, the old nomenclature as shown in Figure 1 is retained here, but the changes are indicated in the discussion below. North Australian Craton Proterozoic rocks crop out in north-west Queensland in the Mount Isa Province as well as the McArthur and South Nicholson Basins and in the north as the Etheridge Province in the Georgetown, Yambo and Coen Inliers and Savannah Province in the Coen Inlier. -

Develop a grazing industry perspective: Snapshot of what graziers and pastoralists think. Conservation for enterprise/income diversification? What conservation models would work? Where? How? What are preferred contractual conditions? . Establish foundation for a strategic industry position on potential supply of environmental services. Enhance the ability of potential investors to understand the needs of pastoralists. Support market formation and negotiations about the provision of contractual biodiversity conservation by pastoralists.
