1. New seismic data releases from South Australia

Geoscience Australia acquired a deep crustal seismic reflection line in July 2008 over the Curnamona Province. Magnetotelluric data was also acquired along the line at 10 km spacing. The 262 km north-south line runs parallel to the eastern shore of Lake Frome, and forms a link to the seismic line acquired by Geoscience Australia in 2003 (03GA-C1).

The un-interpreted processed data for this survey will be released at the Broken Hill Exploration Initiative Conference at the end of September 2009. The time-series (un-interpreted) magnetotelluric data will also be released.

2. Broken Hill Exploration Initiative Conference

The Broken Hill Exploration Initiative Conference (BHEI 2009) will be held from 29 September - 1 October 2009 and will report on new insights into exploration geoscience in the Curnamona Craton and adjacent areas. The conference is being organised jointly by the New South Wales Department of Primary Industries, Primary Industries and Resources South Australia, and Geoscience Australia.

3. New seismic data releases from the Northern Territory

As part of the Onshore Energy Security Program Geoscience Australia, in collaboration with the Northern Territory Geological Survey, has completed a deep seismic reflection survey across the Georgina Basin and Arunta Inlier, and into the Amadeus Basin. The survey commenced at the end of May and was completed in mid July with 373 km of seismic reflection, gravity and magnetotelluric data being acquired. The aim of this traverse is to enhance the knowledge of the petroleum prospectivity of the Georgina and Amadeus basins, and to investigate the uranium potential of the Arunta Inlier. Data from the survey will be released mid 2010.

4. Radiometric Map of Australia provides new insights into uranium prospectivity

The Radiometric Map of Australia is facilitating rapid assessment of uranium prospectivity from the national scale through to the local scale. An article in the latest issue of AusGeo News briefly describes the concentration of uranium in rocks and regolith, and demonstrates how the new radioelement map of Australia can be enhanced and integrated with other datasets for targeting areas of potential uranium mineralisation.

For further information see the September 2009 issue of AusGeo News.

5. New views of Australia's uranium mineral systems

Recent releases from Geoscience Australia to aid uranium exploration include a review of uranium mineral systems modelling, new maps of uranium igneous rocks and 3D models of uranium systems. An article in the latest issue of AusGeo News reports on a revised conceptual framework for a fresh assessment of Australia's uranium mineral potential and highlights key exploration criteria of practical value. It also outlines generalised models for families of uranium mineral systems with shared characteristics, based on an understanding of the fundamental processes in uranium mineral systems and descriptions of well-documented ore systems.

For further information see the September 2009 issue of AusGeo News.

6. Update on geophysical data releases

The current status of Geoscience Australia's geophysical survey data acquisition is now available in a comprehensive table.

The Cunderdin regional gravity survey data (nominal 500 m - 2 km grid) were released via the Geophysical Archive Data Delivery System (GADDS) on 3 September 2009. The survey covers the Perth, Kellerberrin, Pinjarra and Corrigin 1:250 000 Map Sheets.
