Eromanga Basin

The Mesozoic Eromanga Basin, located in far northwestern New South Wales, represents the shallower shelf areas of the much larger Great Artesian Basin. The New South Wales area is considered distal from the recognised main sediment source, associated with major depocentres in South Australia and Queensland.

Recent re-processing of existing geophysical data and newly acquired seismic data has led to the recognition of troughs underlying the Eromanga Basin including the Paka Tank and Urisino troughs.
