Summary of results. Joint NTGS-GA geochronology project : August 2003-December 2003

This record presents new SHRIMP U-Pb zircon geochronology from the Arunta Region and Pine Creek Orogen that were obtained through the NTGS-GA geochronology project in the period August-December 2003.
Four samples were analysed from the Pine Creek Orogen to place timing constraints on the deposition of the sedimentary succession. Two samples of volcaniclastic sediments from the Wildman Siltstone (Mount Partridge Group) give maximumdeposition ages of 2025 +8/-5 Ma and 2029 ± 12 Ma, that are likely to be close the timing of volcaniclastic sedimentation. In contrast, two samples of the Gerowie Tuff from the overlying South Alligator Group have homogeneous zircon populations with ages of 1864 ± 3 Ma and 1862 ± 3 Ma, which are interpreted to reflect the timing of volcaniclastic sedimentation. This is significantly younger than the previously published conventional U-Pb zircon age of 1885 Ma for the South Alligator Group. A sample of presumed metavolcanic rock from the Masson Formation in the South Alligator Valley produced nil zircon.
Zircons from ten samples of igneous and metasedimentary rocks from the Arunta Region were separated and mounted, of which seven had zircons suitable for analysis. Three metasedimentary rocks from the northern Arunta were successfully analysed. A greywacke from the Lander Rock beds in the Walkeley Hills (MOUNT SOLITAIRE1) has a dominant youngest detrital zircon population that provides a well constrained maximum deposition age of 1869 ± 4 Ma. In the Wabudali Range, the Lander Rock beds have a more complex provenance with a spectrum of ages from 3200 to 1825 Ma, and a maximum deposition age of 1847 ± 26 Ma. These are overlain by the Mount Thomas Quartzite of the Reynolds Range Group, which has a maximum deposition age in the Wabudali Range of 1834 ± 38 Ma.
Three granites from MOUNT SOLITAIRE were analysed and all gave ages in the range 1805–1800 Ma. A sample of the Redhackle Granite from southwestern MOUNT PEAKE has an age of 1772 ± 3 Ma, with indications of a metamorphic overprint at 1580 Ma. The Wabudali Granite yielded only metamict zircons.

Geological and energy implications of the Pine Creek region airborne electromagnetic (AEM) survey, Northern Territory, Australia

Funded by the Australian Government's Onshore Energy Security Program the Pine Creek airborne electromagnetic (AEM) survey was flown over the Pine Creek Orogen and parts of the McArthur, Victoria River and Daly Basins in the Northern Territory between August 2008 and 24th May 2009. 
The survey comprises three survey areas: Kombolgie, east of Kakadu National Park; Woolner Granite, near Darwin; and, Rum Jungle, west of Kakadu National Park.  The Pine Creek survey was the second regional AEM survey flown in Australia.
The survey cost of $3 745 000 included a 29 900 line km flown at various line spacings (555m, 1666m and 5000m) and covered approximately 74 000 km2. The Woolner Granite and Rum Jungle survey areas were flown by Fugro Airborne Surveys Pty. Ltd. (FAS), for Geoscience Australia (GA), using the TEMPESTTM time-domain AEM system. The Kombolgie survey area was flown by Geotech Airborne Pty. Ltd VTEMTM time-domain AEM system.
The Pine Creek AEM survey was designed to deliver reliable, pre-competitive AEM data to promote exploration for uranium, copper-gold, base metals, tin and nickel in both brownfields and greenfields areas. The survey area hosts several uranium deposits, including the Ranger Uranium Mine, Rum Jungle and Nabarlek.

GSWA Mt Barker TMI Grid Geodetic

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This GSWA Mt Barker TMI Grid Geodetic has a cell size of 0.00042 degrees (approximately 42m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2012 by the WA Government, and consisted of 126090 line-kilometres of data at a line spacing between 200m and 300m, and 50m terrain clearance.

North Bowen Basin: Conventional oil and gas package

Publicly available data was compiled to provide a common information base for resource development, environmental and regulatory decisions in the north Bowen Basin. This data guide gives an example of how these data can be used to create the components of a workflow to identify conventional hydrocarbon resource (oil and gas) opportunities. The data guide is designed to support the data package that provide insights on conventional oil and gas resources in the north Bowen Basin.
The conventional hydrocarbon assessment for the north Bowen Basin includes 4 of the 5 geological intervals, termed plays – these intervals have been defined by Wainman et al. (2023). The assessment captures data from well completion reports and government data sources (e.g. Queensland Petroleum Exploration Database (QPED) from the Geological Survey of Queensland (GSQ) Open Data Portal and the Bowen and Surat Basins Regional Structural Framework Study (SRK Consulting, 2008)) to inform the 5 components required for conventional hydrocarbons to be present. These datasets are used to map out gross depositional environments and their geological properties relevant for conventional hydrocarbon assessments. From these datasets, the following properties were evaluated and mapped across the basin: reservoir presence, reservoir effectiveness, top seal, trap and charge.
The data are compiled at a point in time to inform decisions on resource development activities. The data guide outlines the play-based workflow for assessing conventional hydrocarbon resource prospectivity. Each of the elements required for a prospective conventional hydrocarbon system is explained and mapped. These data were merged and spatially multiplied to show the relative assessment of conventional hydrocarbon prospectivity across the north Bowen Basin, at both the play interval and basin scale. As an example of assessments contained within the data package, this data guide showcases the conventional hydrocarbon prospectivity of the Upper Back Creek Play interval.

Magnetotelluric data and model for the 09GA-GA deep magnetotelluric transect

This dataset contains magnetotelluric data and a 3D inversion model from the 09GA-GA1 deep magnetotelluric transect, collected in Central Australia in 2009. The transect is 350 km long, with data acquired from 18 stations with both broadband and long period instrumentation, and 21 stations with broadband instrumentation only (a total of 39 sites).  The resulting station spacing is 10km for the broadband stations, and 20km for stations with both broadband and long period instrumentation. We have reprocessed the broadband data using the Bounded Influence, Remote Reference Processing software (BIRRP), yielding an extended bandwidth of 0.003 to 1300 s and merged these data with the long period data. We have inverted the data using the ModEM 3D inversion code.
