Presented at the Evolution and metallogenesis of the North Australian Craton Conference, 20-22 June 2006, Alice Springs. The southern Arunta region contains a number of small (<5 Mt) Zn-Cu-Pb (Ag-Au) deposits. Although none of these deposits are economic, they do indicate a moderate level of base-metal potential for this region. Most of these deposits are located in the Strangways Range, which forms part of the Aileron Province. These deposits were classified as Oonagalabi-type deposits by Warren & Shaw (1985), citing similarities in metal assemblages, alteration assemblages, and host units, and interpreted as volcanic-hosted massive sulphide (VHMS) deposits. More detailed geological mapping and geochemical and geochronological data suggest that the Oonagalabi group should be subdivided further into three types, the Utnalanama-type, the re-defined Oonagalabi-type and the Johnnies-type (Hussey et al., 2005). <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>

An overview of mineral exploration within Australia for the year 2000.

This dataset is part of a digital geological map of the Granites-Tanami Block which Australian Geological Survey Organisation has prepared by joining together as a seamless coverage 15 of the 1:250 000 geological maps which cover the province.The data layers in the digital map include geology, faults, lineaments structural data, mineral deposits and Australian Geological Survey Organisation drill hole locations. The digital data is available in Arcinfo/ Arcview or Mapinfo format. Topographic and cultural layers are not included: these can be purchased separately from AUSLIG.

Package comprises a digital compilation of regional mapping of Bathurst (SI5508) 1:250 000 map by AGSO and NSW Department of Mineral Resources, under NGMA from 1991 to 1996.

Detailed analysis and modeling of regional gravity and magnetic datasets from the Stuart Shelf around the Olympic Dam iron oxide-copper-gold (IOCG) deposit, constrained by geological observations from deep drillcores, show that the eastern Gawler Craton at 1.61-1.59 Ga consisted of an Archean core with two volumes of supracrustal successions stepping out eastward from it. This pattern is consistent with that displayed on the Eyre Peninsula. Detailed models of potential-field data show no evidence for the presence of widespread mafic rocks or extensional basin systems developed immediately prior to, or during, IOCG mineralization. The high intrusive level, and geometry of Hiltaba Suite plutons emplaced immediately prior to IOCG mineralization is difficult to explain in terms of a genetic association with mantle plumes, continental extension, or rifting. Instead, the tectonic setting inferred from the basement architecture during mineralization is one of low-strain compression, based on geometric considerations. A case can be made for mild extension in a localized accommodation zone during emplacement of the Hiltaba Suite and Gawler Range Volcanics, in an overall orogenic setting with northwest-southeast directed tectonic transport in present coordinates. An IOCG minerals system produced during low-strain compression is consistent with maximum rates and volumes of fluid flow in the upper crust, and access of these fluids to a variety of basement rock types to buffer metal-scavenging fluids. This fluid-driving mechanism does not require, or implicate, a genetic role for regional mafic magmatism and volcanism synchronous with IOCG mineralization. The approach used in this study is generally applicable to exploration for IOCG systems, and other mineral systems in covered terranes that have distinctive geophysical signatures resulting from redox fluid-wallrock geochemical reactions.
