Figure explanation: Crustal Bouguer gravity anomaly basemap of the Carnarvon basin. Contour interval is 10 mgals. The crustal Bouguer was generated by calculating and removing the gravity effect of the bathymetry from the GEOSAT Free-air gravity anomaly. A long-wavelength trend associated with the east-to-west crustal thinning across the northwest Australian margin was removed from the 2'x2' GEOSAT free-air gravity data. The most prominent features are: 1) positive anomalies associated with the location of the ocean-continent boundary and the Ranking trend, Alpha Arch, and Jurabi Horst (JH on map), and 2) negative anomalies that correlate with the eroded southwest margin of the Exmouth Plateau, the Exmouth, Barrow and Dampier sub-basins, and the Kangaroo Trough. Shown are the location of four modeled cross-sections, corresponding to seismic lines (from south to north) AGSO110-11, AGSO110-12 & 93BA-38, GPCT93-406 & 93BA-10, and AGSO101R-09.
