1. New Geoscience Australia Record released - A Review of the Geochemical Processes Controlling the Distribution of Thorium in the Earth's Crust and Australia's Thorium Resources

The new Geoscience Australia Record reviews the geochemistry of thorium in the Earth's crust and the geology and distribution of Australia's thorium resources. The record can be downloaded from the Geoscience Australia website. Exploration for thorium to date has been minimal and there are no comprehensive records of resources, mainly because of a lack of large-scale commercial demand.

Geoscience Australia's Thorium project was established as part of the Onshore Energy Security Program to gain a better understanding of the geochemistry of thorium in the Earth's crust and to obtain an improved understanding of the status and distribution of Australia's thorium resources. Currently, there is renewed interest in thorium because it produces much less plutonium and other transuranic elements than is produced in uranium fuel cycles.

2. Surface Geology of South Australia - 1:1 million scale data release in June 08

The next installment of the 1:1 million digital geology of Australia was released in June. The Surface Geology of South Australia is available as shapefiles and ESRI export files for use in most common GIS applications. The data set was compiled mainly from PIRSA's digital 1:250,000 scale mapping, is seamless across the state, and has been edgematched with adjoining states and the Northern Territory. Polygons and linework are fully attributed with geological unit names, ages and lithological descriptions.

The data are available as a free download or purchase on CD for A$99 via the Geoscience Australia website.

Users should note that Ordovician and younger units in the current South Australian data set have not been reviewed by PIRSA staff, and thus these data should be considered as preliminary.

For more information email, Ollie Raymond or phone +61 (0)2 6249 9575.

3. Onshore Energy Security Program update

The Onshore Energy Security Program (OESP) data acquisition for the deep crustal seismic reflection survey in the Darling Basin, conducted in conjunction with the New South Wales Department of Primary Industries, has been completed. The airborne electromagnetic survey in the Paterson region (Western Australia) is nearing completion whilst the survey in the Pine Creek region (Northern Territory) is expected to commence later this year

For further information on the seismic program email, Jenny Maher or phone +61 (0)2 6249 9896; or on the AEM surveys email Alan Whitaker of phone +61 (0)2 6249 9702

4. Update on geophysical data releases

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

Requests for quotation closed on Wednesday 18 June for provision of gravity data over the Windimurra region of the Yilgarn Craton of Western Australia.

For further information, email Murray Richardson or phone +61 (0)2 6249 9229.

5. Useful Geoscience Australia websites

Geoscience Australia's website provides easy access to a comprehensive range of free maps and publications of interest to mineral explorers.
