Abstract:
This paper brings up to date our understanding of basement geology in the region of the central Australian basins as a result of an ongoing AGSO project to produce a Basement Tectonic Map of Australia at 1:5 000 000 scale based on regional magnetic and gravity data. The gravity data used in this study include: (1) data recently integrated into a 5 km gridded format, (2) contoured Bouguer anomaly maps (BMR 1976a, Morse et al. 1991) or (3) images (Morse et al. 1992, Milligan et al. 1992). Magnetic data, generally collected along 1.5 km line spacing and 150 m terrain clearance, have been studied in the form 1:1 000 000 and 1:2 500 000 maps (BMR 1976b) as well as computer generated images at various scales including the 1:5 000 000 map of Tarlowskii et al. (1993) covering the whole of Australia.
