1. Release of the Frome Embayment TEMPEST airborne electromagnetic (AEM) survey: Inversion report and data package (200m)
To accompany the Frome AEM Survey interpretation record is a new Geoscience Australia Layered Earth Inversion to 200 metres is now available for free download on the Airborne Electromagnetics Project page. The data, which are provided in formats that can be viewed on most computer systems, include JPEG images (.jpg) with associated word files for easy use in geographic information system (GIS) packages, ER Mapper grids (.ers) and point located ASCII data with relevant metadata for derived products. In addition, in this data release the georeferenced images are delivered with a linear colour stretch as well as a logarithmic colour stretch to aid interpretation.

The Albany-Fraser Orogen Seismic Survey in south eastern Western Australia was completed in June 2012. A total of 672 kilometres of deep crustal seismic reflection data and gravity data were acquired along four seismic lines across the Albany-Fraser Orogen. Magnetotelluric data were also acquired over areas of interest. The data quality for the survey is excellent, including a section over buried limestone along the eastern end of the 12GA-AF3 Line (Figure 1). This is the first time high quality deep crustal reflection seismic has been recorded over limestone terrains on the Nullarbor Plain. The new data will be processed by Geoscience Australia geophysicists and interpreted by geologists from Geoscience Australia and the Geological Survey of Western Australia.
The survey was a collaborative project between Geoscience Australia and the Geological Survey of Western Australia and is part of the ongoing cooperation under the National Geoscience Agreement. Funding was provided through the Western Australian Government’s Exploration Incentive Scheme. AngloGold Ashanti Australia Limited also joined the seismic acquisition project and funded a deep crustal reflection seismic transect extending for 81 kilometres across the Tropicana gold deposit. This transect was managed by Geoscience Australia on behalf of the National Research Facility for Earth Sounding (ANSIR).
The survey was designed to image the crustal architecture of the eastern Yilgarn Craton margin and investigate its relationship with the Proterozoic Albany–Fraser Orogen as well as image the structural geometry around the Tropicana deposit to help define prospective areas elsewhere within the Albany-Fraser Orogen.

The Geoscience Australia Geochronology Laboratory is hosting the 6th Biennial Sensitive High Resolution Ion MicroProbe (SHRIMP) Workshop in Queensland from 1-4 August 2012 to discuss, debate and celebrate all matters SHRIMP. The workshop will immediately precede the 34th International Geological Congress in Brisbane starting on 5 August 2012.
For more details on the workshop and to download the fourth circular, please go to the SHRIMP Workshop website.

Australia's largest ever Geoscience Event, featuring a strong resources and energy program.
The Scientific Program for the IGC is now available.
Join more than 5000 international geoscientists at the Brisbane Convention and Exhibition Centre for the 34th IGC, 5-10 August 2012.
The ACROFI Workshop provides an international forum for exchange of the latest research results and ideas between geoscientists from academia, government and industry from Asian countries and other nations. The conference will focus on applications and new developments for the study of fluid and silicate-melt inclusions. The workshop will immediately follow the 34th International Geological Congress in Brisbane.
For more details on the workshop please go to the ACROFI IV website.
