Fig. 8

Cross sections for profile X-X’ in Fig. 1. (a) Elevation; (b) depth to Proterozoic basement; (c) Bouguer gravity (black line) and modelled (blue line); (d) resistivity from 3D model, density (in g/cm3) derived from regional shear-wave velocity model47. Also shown are: thick black dashed line as an inferred Moho defined by the 3.3 g/cm3 density; medium black dashed line AusMoho38; thin black dashed line depth to Proterozoic basement; white dots are depths to idealised line-source for gravity anomalies G1-G4. Cratons and Provinces: MP - Musgrave Province; AP – Arunta Province. Basins: OB – Officer Basin; AB – Amadeus Basin; GB – Georgina Basin; NB – Ngalia Basin.
