Geoscience Australia will be hosting two one-day seminars to present the results of its research to the mineral exploration community later this year. Full details of the seminar program are currently being finalised.
The first seminar will be held in Brisbane at The Eagle Street Conference Centre on Tuesday 18 November and a second will be held at The Esplanade Hotel in Fremantle on Thursday 4 December 2003.
If you would like to receive information on these seminars as it becomes available please contact Mike Huleatt on +61 (0)2 6249 9087 or by email at Mike.Huleatt@ga.gov.au.
Geoscience Australia has now reached agreement with the John de Laeter Centre at Curtin University in Western Australia to access 100 days on the new SHRIMP (Sensitive High Resolution Ion MicroProbe) which is currently being assembled and tested following its delivery in early September.
As part of this increase in geochronology capabilities the Minerals Division recently advertised for a geochronologist, with the intent of basing the successful applicant at Curtin University in Perth. Dr Keith Sircombe, currently with the Tectonics Special Research Centre at UWA was the successful applicant.
Dr Sircombe will commence duties with Geoscience Australia in early November. Keith has extensive experience as a geochronologist. He has worked at three SHRIMP laboratories on two continents (RSES at ANU, Canadian Geological Survey in Ottawa, and John de Laeter Centre at Curtin University) and will form a key member of the new Perth-based Geosceince Australia SHRIMP operations.
In addition the Minerals Division is currently training three new geochronologists to meet the demand for additional age information created through access to the additional SHRIMP days.
The Geological Survey of Western Australia (GSWA) and Geoscience Australia (GA) will be contracting an airborne magnetic, gamma-ray and elevation Survey in the Robinson Range and Belele area of Western Australia.
The project comprises acquisition, processing and supply of 29,161 line kilometres of airborne magnetic, gamma-ray and elevation data. The line spacing at the Survey will be 400 metres and the nominal flying height will be 60 metres above ground level. The gamma-ray spectrometer downward looking crystal volume is to be 33 litres. The survey should commence in early October 2003. Geoscience Australia will manage the data acquisition and processing components of the initiative.
GSWA is also purchasing additional modern airborne data to complete the coverage of the Robinson Range and Belele 1:250 000 Sheet areas and will acquire 23,860 line kilometres of 200 metre-spaced Murchison multi-client airborne magnetic and radiometric data covering part of the Belele and Cue map sheets. A combined dataset will be released subsequent to the flying of the new survey.
Information derived from these geophysical data and other complementary datasets will be used extensively to assist in the geological mapping of the Archaean rocks and is aimed at stimulating mineral exploration activity in this prospective region of Australia.
As part of the Burakin Airborne Survey flown in May 2003, tie lines were flown in order to enable the reprocessing of 3 newly purchased modern gradiometer airborne magnetic, gamma-ray and elevation datasets. Geoscience Australia will be contracting the reprocessing of the Goomalling, Mount Marshall and Lake Hillman (Western Australia) airborne magnetics, gamma-ray and elevation data.
The contract should commence in late September 2003 and be completed by early November 2003. Information derived from these geophysical data and other complementary datasets will be used extensively to assist in the geological mapping and is aimed both at stimulating mineral exploration activity in this prospective region of Australia, and in environmental and regolith research studies. The project comprises reprocessing and supply of approximately 94,160 line kilometres of airborne magnetic data, gamma-ray and elevation data.
