Four land seismic surveys were proposed over the Northern Territory: • Southern McArthur Basin, crossing the Batten Trough. • The Tanami region and north-western Arunta. • Central Arunta, extending the existing BMR seismic line north-easterly across the Wiso Basin, the Tennant Creek Province and the Georgina Basin. • Two north trending transects in the Eastern Arunta, beginning in the Amadeus Basin, crossing the Arunta and terminating in the Georgina Basin. Prior to seismic acquisition, potential field modelling was conducted to refine existing geological models. Analysis of the magnetic and gravity fields help to define a number of variables including; the dip of structures and geological contacts, the depths to the tops of bodies, the depth extent of bodies and, the shape and orientation of bodies.
