1. New GA Record released - A Review of the Geochemical Processes Controlling the Distribution of Thorium in the Earth's Crust and Australia's Thorium Resources
The Thorium Project was established as part of the Onshore Energy Security Program (OESP) 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, compared with uranium fuel cycles and is considered by some to present less problems in waste disposal and to be more proliferation resistant than uranium-fuelled reactors.
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. The new GA Record reviews the geochemistry of thorium in the Earth's crust and the geology and distribution of Australia's thorium resources and can now be downloaded from the Geoscience Australia website.
2. Surface Geology of South Australia - 1:1 million scale data release in June 08
The next instalment of the 1:1 million digital geology of Australia was released during 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 $99 via the GA 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.

3. Onshore Energy Security Program update
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

5. Useful Geoscience Australia websites
Geoscience Australia's website provides access to a comprehensive range of Australian topographic maps and data through the National Mapping web page.
