About this survey

Long-period magnetotelluric transfer functions from an Adelaide University transect across the Olympic Dam iron oxide copper-gold deposit, on the margin of the Proterozoic Gawler Craton in South Australia. The survey occupied 58 long-period stations at 5 to 10 km spacing along a 220 km section coincident with the 2003 deep crustal seismic reflection line 03GA-OD1, crossing the deposit and the major crustal boundaries of the region. The transect was designed to delineate crustal structures that may have channelled mineralising fluids, and two-dimensional inversion imaged a low-resistivity region extending through the crust beneath Olympic Dam, with results published as Heinson, Direen and Gill (2006, Geology 34, 573-576, doi:10.1130/G22222.1). This package carries 58 released EDI transfer function files, one per station, with vertical-field transfer functions included at every site.
