Abstract

A seismic survey using the Australian National Seismic Imaging Resource (ANSIR) Hemi 60 Vibroseis vehicles, ARAM24 acquisition equipment and Pelton controllers was carried out in the Curnamona Province of South Australia. A total of 197.6 km of 2-D seismic reflection data were collected to 18 seconds two way time over a single line at a nominal 60 fold CDP coverage. These data were acquired under contract by Trace Energy Services (2003) and by Terrex Seismic (2004). The survey commenced in August 2003 but was abandoned due to wet weather. Survey operations were recommenced and completed in July 2004. The project was undertaken to meet the objectives of ANSIR proposal 03-02R as lodged by researchers from PIRSA, Office of Minerals, Energy and Petroleum, SA. The principal scientific objective of this survey was to provide a regional crustal seismic image of the Curnamona Province. This dataset will assist in the understanding of the geological architecture and resource potential of the region particularly in areas under cover. This line links with a seismic transect in the Broken Hill Block undertaken by Australian Geological Survey Organisation (AGSO, now Geoscience Australia) in 1996 and provides a future opportunity for an eventual east-west continuation across the Adelaide Geosyncline and the Gawler Craton. The survey was funded by PIRSA, Office of Minerals, Energy and Petroleum, SA and the pmd*CRC with project supervision undertaken by ANSIR and in-kind support from Geoscience Australia (GA).

Lineage

The Curnamona Province deep crustal seismic survey was carried out in August 2003 and July 2004 across the southern Curnamona Province in South Australia as a collaborative project between PIRSA Minerals and Energy Resources, the predictive mineral discovery Cooperative Research Centre (pmd*CRC) and Geoscience Australia, using the facilities of ANSIR (National Research Facility for Earth Sounding). The overall aim of the survey was to provide information on the crustal architecture of the southern Curnamona Province in both the highly prospective Palaeo- and Mesoproterozoic rocks and the overlying Neoproterozoic and Cambrian successions. A particular objective was the imaging of the deeper crust and major structural features that may have influenced hydrothermal fluid flow, and hence mineralisation. The survey results also provide fundamental information relevant to exploration for geothermal energy.
