1. Workshop on new seismic and MT datasets in South Australia

There will be a one-day workshop on Thursday 6 May 2010 in Adelaide to present the results of new seismic reflection and refraction and magnetotelluric data collected during 2008 and 2009 in South Australia in conjunction with the Department of Primary Industries and Resources, South Australia.  The seismic lines presented include the Curnamona, Gawler-Curnamona link, Arrowie and Eyre Peninsula transects.

To obtain more details on the workshop and register see the South Australian Seismic and MT workshop flyer [PDF 533KB].

2. Workshop on Paterson airborne electromagnetic survey  

Geoscience Australia is presenting results from its 49 000 km2 Paterson airborne electromagnetic (AEM) survey at a free workshop in Perth on Tuesday 4 May 2010. The workshop will include presentations by Geoscience Australia on the data acquisition, processing, inversion, geological interpretations and implications for uranium and other mineral system exploration. There will be several industry presentations on how companies have been using and interpreting the AEM data. Fugro Airborne will present a case study also on how the TEMPEST AEM system can be used in regional mapping applications. The workshop will include an open forum to discuss the results in more detail.

To obtain more details on the workshop and register see the Paterson AEM workshop flyer [PDF 315KB].

3. Onshore Energy Security Program update

Geoscience Australia’s Onshore Energy Security Program is designed to reduce risk in exploration and support development of Australia’s onshore energy resources. An article in the March 2010 issue of AusGeo News reports on the release of data from: the Paterson Province and Pine Creek Orogen airborne electromagnetic surveys; seismic reflection, gravity and magnetotelluric surveys in South Australia; and the National Geochemical Survey of Australia.

4. Preliminary Soil pH map of Australia

Data gathered in the field during the sample collection phase of the National Geochemical Survey of Australia has been used to compile a preliminary Soil pH Map of Australia. The map provides fundamental datasets which can be used for mineral exploration and resource potential evaluation, environmental monitoring and land use policy development.

For further information see the March 2010 issue of AusGeo News.

5. Exploring for sandstone-hosted uranium deposits in paleovalleys and paleochannels

Significant sandstone-uranium deposits are located in fluvial (or river) sediments filling paleochannels. An article in the March 2010 issue of AusGeo News compares the geology of sandstone-hosted uranium deposits in the Lake Frome region of South Australia with the Monument Valley and White Canyon districts in the United States. Mineralisation is often located at the bends and/or sites of confluences of the main channel with tributaries frequently occupying basement scours filled with coarser sediments.

6. Update on date on geophysical data releases

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

Quotation request for the Frome Airborne Electromagnetics (AEM) was released on 24 March and closes on 14 April 2010. The survey covers the Marree (pt), Callabonna (pt), Copley (pt), Frome (pt), Parachilna (pt), Curnamona, Olary (pt) and Chowilla (pt) 1:250 000 Map Sheets.
