Seismic reflection data obtained across this basin have the potential to revolutionise our understanding of the crustal architecture in which this deposit formed. These data were collected in late 2002 as part of a study to examine the fundamental basin architecture of the Southern McArthur Basin and the nature of underlying basement. Much of the seismic program was designed to test geometric models in this area, including tectonostratigraphy, fault systems and basement structure. The results have wider applicability because the basin is considered to be a little deformed analogue of the Western Succession of Mt Isa. The main seismic line (02GA-BT1) was oriented east-west across the Southern McArthur Basin, commenced 15 km west of Borroloola, and extended about 110 km westwards along the Borroloola-Roper Bar road. A short north-south cross line (02GA-BT2), 20 km long, was acquired within the basin itself, in collaboration with AngloAmerican. {"type": "Polygon", "coordinates": [[[135.0, -16.5], [136.5, -16.5], [136.5, -16.0], [135.0, -16.0], [135.0, -16.5]]]} 135.0 136.5 -16.5 -16.0 AU-NT Earth Sciences GA Publication Published_External Record sedimentary basins seismic sections seismology Download the Record (pdf) documentDigital Download the Record (pdf) PDF Unnamed resource documentDigital HTML
