Darling Basin

The Darling Basin, located in western-central New South Wales, is an intra-cratonic and highly structured depositional centre filled with mostly Devonian sedimentary rocks reaching up to 8 km in thickness. The Darling Basin is overlain by the Mesozoic Eromanga Basin to the north and by the Cenozoic Murray Basin to the south. Covering an area of over 100,000 km2 it is one of Australia's largest underexplored basins.

Modern A 3D structural framework of the basin was developed using aeromagnetic, gravity and seismic data (2,000 km of modern multi-fold seismic data was recently acquired by the Department and has been supplemented by reprocessed old seismic data).
