Data

Magnetotelluric surveys acquired along the southern part of the GOMA (Gawler Craton, Officer Basin, Musgrave Province, Amadeus Basin) deep seismic reflection transect (GA08-OM1) from Tarcoola to near Coober Pedy in South Australia (beside the Adelaide-Darwin railway line), collected in December 2008

Full description

In December 2008, magnetotelluric (MT) data were acquired by Geoscience Australia (GA) along the southern part of the GOMA (Gawler Craton, Officer Basin, Musgrave Province, Amadeus Basin) deep seismic reflection transect (GA08-OM1) from Tarcoola to near Coober Pedy in South Australia (beside the Adelaide-Darwin railway line) as part of the Australian Governments Onshore Energy Security Program. With pre-existing long period MT data to the north (Selway, 2006; Selway et al., 2011), there are now MT data for a 540 km profile along most of the seismic line. The new MT data were acquired along a ~230 km profile at 27 sites, with site spacings ranging from 5 to 20 km. The aim of the MT survey was to produce a two-dimensional image of the electrical resistivity structure of the crust and uppermost mantle. The MT information is complementary to that obtained from deep seismic reflection, gravity, magnetic and geological data, which together provide new knowledge of the crustal architecture and geodynamics of the region, which is important for helping to assess the potential for both mineral and energy resources.
