Presented at the Evolution and metallogenesis of the North Australian Craton Conference, 20-22 June 2006, Alice Springs. Over a half (570) of the known uranium occurrences in Australia are located in the North Australian Craton and the overlying Ngalia, Amadeus, and McArthur River basins. These occurrences include 43 uranium deposits with recorded resources. The uranium occurrences and deposits show a general spatial relationship to uranium-enriched felsic igneous rocks. The total uranium resource (production + resources) of the North Australian Craton and the overlying basins amount to about 510,000 t U3O8. The bulk of these resources are accounted for by the following: unconformity type in the Pine Creek Orogen (~420,000 t U3O8), sandstone uranium (~36,000 t U3O8) in the McArthur, Amadeus and Ngalia Basins, metasomatite (~38,000 t U3O8) and metamorphic deposits of the Mt Isa Orogen, and calcrete deposits in Arunta. <p>Related product:<a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=64764">Evolution and metallogenesis of the North Australian Craton Conference Abstracts</p>

Presented at the Evolution and metallogenesis of the North Australian Craton Conference, 20-22 June 2006, Alice Springs. The 2005 Tanami Seismic Collaborative Research Project was developed to provide a better understanding of the crustal architecture and mineral systems of the Tanami region within Western Australia and the Northern Territory. This was achieved through the acquisition of four regional scale deep crustal seismic reflection profiles. The Tanami Seismic Collaborative Research Project involved Geoscience Australia, the Northern Territory Geological Survey, the Geological Survey Western Australia, Newmont Exploration Pty Ltd and Tanami Gold NL. <p>Related product:<a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=64764">Evolution and metallogenesis of the North Australian Craton Conference Abstracts</p>

Presented at the Evolution and metallogenesis of the North Australian Craton Conference, 20-22 June 2006, Alice Springs. The North Australia Project of Geoscience Australia had, as its starting point, the review of event chronology in the Arunta Region compiled by Collins and Shaw (1995) and only sparse dating coverage in the Tanami and Tennant regions. The knowledge-base was still dominated by younger systems, which overprinted the Palaeoproterozoic rocks. Early attempts to unravel the pre-1700 Ma evolution with SHRIMP U-Pb dating had not yet identified all of the major event systems and their scope. In the absence of detailed timing constraints, regional correlations were conjectural or based on perceived litholigical links. The prevailing model was that the earliest evolution across the Proterozoic inliers of northern Australia comprised two major basin phases separated by a single correlated orogenic episode, the 'Barramundi Orogeny', which created and defined the North Australian Craton as a tectonic domain (Etheridge et al., 1987, Meyers et al., 1996). Detailed regional re-mapping, combined with a program of imaging-assisted SHRIMP U-Pb dating studies, has led to a new understanding. Several distinct events are now recognised and there are many basin phases separated by a variety of stratigraphic and/or tectonic surfaces. Although major issues are yet to be resolved, there is greater confidence in reconstructing the evolution and metallogeny of individual regions. Some key inter-region correlations can now be demonstrated at the scale of individual formations, unconformities or events. <p>Related product:<a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=64764">Evolution and metallogenesis of the North Australian Craton Conference Abstracts</p>

Presented at the Evolution and metallogenesis of the North Australian Craton Conference, 20-22 June 2006, Alice Springs. Strikingly similar geological histories and metal endowments support the view that the Broken Hill (Curnamona craton) and Mt Isa regions were once contiguous, or at least formed part of a single continuous Zn-Pb and/or IOCG mineral province, during the late Palaeoproterozoic-early Mesoproterozoic (Giles et al., 2004). Pb model ages for major Zn-Pb deposits like Broken Hill and Cannington (1675 Ma and 1665 Ma respectively) are comparable (Carr et al., 2004) and high grade metasedimentary rocks hosting these deposits are thought to have been deposited at about the same time (ca 1690-1670 Ma) in either an intra-continental rift or a back-arc extensional environment (e.g., Blake, 1987; Walters and Bailey 1998; Betts et al., 2003). High grade deformation and metamorphism at 1580-1600 Ma (e.g., Page and Sweet, 1998; Page et al. 2004) preclude unequivocal identification of the original ore-forming environment in both cases, although clues to the tectonic setting and kinematic framework are still preserved in less intensely metamorphosed rocks of equivalent age in the Mount Isa Western Succession. The Western Succession rocks developed over a 200-Myr period from 1.8 Ga to 1.6 Ga (Blake, 1987) and, thus, overlap in age with five major tectonothermal events (Claoué-Long, 2003; Scrimgeour, 2005) recognised in the Arunta-Tanami region of the NAC. Major events identified at 1810 Ma and 1770 Ma (Stafford and Yambah), 1730-1700 Ma (Strangways), ~ 1640 Ma (Leibig) and 1560-1590 Ma (Chewings) in the NAC also find expression in the Mount Isa and Broken Hill regions (Page et al., 2000; Neumann et al., 2006), inviting speculation that the crustal processes and geodynamic framework inferred for these two regions are equally pertinent to the mineral provinces in the southern and eastern NAC.

This map has been created to support the Taruman illegal fishing court case, and is part of a map series. It shows recorded suspected long line locations and aerial photograph locations within Australia's AFZ around Macquarie Island for Exhibit 11/09/05-4.1, Exhibit 11/09/05-4.3, and Exhibit 14/09/05-1.1. It also shows the "MaxSea" ship locations for the Taruman with the additional longline coordinates added to the ship locations but does not show the ship route.
