3D Gravity Models of the Capel and Faust Basins, Lord Howe Rise

This report is part of a set delivered by Geoscience Australia on interpretation of data acquired during the summer of 2006/07 on seismic reflection, refraction and potential field survey GA-302.

A 3D approach to the gravity modelling was necessitated by the irregular geological structure of depocentres and basement highs. Over 6000 m of sediment is interpreted in the deepest pockets.

The tools developed to realise the 3D gravity modelling are described in some detail. The gravity modelling process is also presented with a view to easing the integration of 3D mapping methods with a traditional reflection seismic interpretation workflow in the marine sedimentary basin environment.
