Minerals Alert October 2011

A monthly online newsletter with product news, data releases and projects relating to the minerals and energy exploration industry.

1. Release of Onshore Energy Security Program magnetotelluric data from deep crustal seismic transects

For the first time, magnetotelluric (MT) data acquired through the Onshore Energy Security Program can be downloaded from the Geoscience Australia website. Surveys have been conducted by Geoscience Australia under its Onshore Energy Security Program along deep crustal seismic reflection transects, in collaboration with the University of Adelaide, the Geological Survey of South Australia, Primary Industry and Resources South Australia, the Northern Territory Geological Survey, Geological Survey of Queensland and the Australian National Seismic Imaging Resource.

MT data are available for five surveys:

Data can be downloaded at the Seismic Acquisition and Processing Project web page.

These data include the industry-standard electrical data interchange (EDI) files, location information and reports.

For further information, please email tanya.fomin@ga.gov.au; or phone +61 2 6249 9896.  

2. Seismic data and workshop for the Capricorn survey, Western Australia

The Capricorn deep crustal seismic survey was acquired in 2010 and extends almost 600km from the Pilbara Craton, across the Hammersley Basin and the Capricorn Orogen, to the Yilgran Craton in Western Australia. This survey was a collaborative project between Geoscience Australia, AuScope, and the Geological Survey of Western Australia. Funding came from Geoscience Australia’s Onshore Energy Security Program, AuScope Earth Imaging and Western Australia’s Royalties for Regions Exploration Incentive Scheme. The survey consists of three traverses with a total length of 581km. These seismic and gravity data aim to image the extent of the Archean crust beneath the Capricorn Orgeny and identify the relationship between the Pilbara and Yilgarn cratons.

The processed SEG Y data, TIFF images, location information, and gravity data are available as a free download.

To obtain further details on the seismic data, please email tanya.fomin@ga.gov.au; or phone +61 2 6249 9896.

There will be a full day workshop on Wednesday 23 November 2011 in Perth to present the results of Capricorn seismic reflection and magnetotelluric data. The survey and the workshop are a joint venture involving Geoscience Australia, the Geological Survey of Western Australia, AuScope, ANSIR and the University of Adelaide.

Registrations are through the Geological Survey of Western Australia.

To obtain further details on the workshop, please email russell.korsch@ga.gov.au; or phone +61 2 6249 9495.

3. Frome airborne electromagnetic survey data interpretation workshop, 30 November 2011

Geoscience Australia and Primary Industries and Resources South Australia (PIRSA) will hold a one day workshop on interpretations and implications from the Frome airborne electromagnetic (AEM) survey. Workshop speakers will include staff from Geoscience Australia, PIRSA and industry, and will detail highlights from the survey data.

The workshop will be held on 30 November 2011 between at 9:00 am and 4:00 pm in the University of Adelaide Department of Geology and Geophysics Mawson Theatre and will include morning refreshments and a light lunch. Attendance is free, but please advise your attendance for catering purposes.

For more information, or to reserve a seat, contact Dr Ian Roach, Geoscience Australia. Email Ian.Roach@ga.gov.au, Ph +61 2 6249 9683.

4. Release of the uranium and geothermal prospectivity assessment of east-central South Australia

Geoscience Australia has released Geoscience Australia Record 2011/34, An assessment of the uranium and geothermal prospectivity of east-central South Australia. The report presents an assessment of the uranium and geothermal energy prospectivity of east-central South Australia using a GIS-based geosystems approach, utilising regional datasets, including geophysical, geological, geochemical and aquifer data. Uranium systems considered include sandstone-hosted, iron-oxide copper-gold-uranium, unconformity-related and sediment-hosted copper-uranium. Both hot-rock and hot sedimentary aquifer geothermal systems were considered. The analysis highlights known prospective districts as well as new areas, including extensions of known districts under cover.

The report is available as a free download.

For further information, please email david.huston@ga.gov.au; or phone Dave Huston +61 2 6249 9577.

5. Major International Resources and Energy Event, 34th International Geological Congress (IGC), Brisbane 5-10 August 2012

Under the theme Unearthing our Past and Future - Resourcing Tomorrow, around 40 per cent of the IGC scientific program will be of direct interest to the resources and energy sectors. Each of the five days of Congress sessions will have several symposia on minerals, petroleum and energy.

Further details on the event will be available with the publication this month of the Third Circular.

6. 6th International SHRIMP Workshop, 1-4 August 2012

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 first circular, please go to the SHRIMP Workshop website.

For further information, please email SHRIMP2012@ga.gov.au; or phone Keith Sircombe on +61 2 6249 9543 or Emma Chisholm on +61 2 6249 9044.
