Palaeoproterozoic orogens form widespread and prospective basement (eg Pine Creek Orogen, Aileron Province, Tanami Region, Tennant Region), with protolith ages most commonly in the range 1.87-1.73 Ga. Further south, the Warumpi and Musgrave provinces represent more juvenile crust with ages of 1.69-1.07 Ga. Widespread Palaeo-Mesoproterozoic basins (McArthur, Tomkinson, Birrindudu and South Nicholson basins) overlie much of the North Australian Craton and are connected beneath younger basins. The Neoproterozoic to Palaeozoic basins were linked for much of their history, but were substantially affected and dismembered by intraplate tectonics in central Australia. The Kalkarindji Province records a widespread Cambrian flood basalt event over much of the northern part of the Territory. Mesozoic to Cenozoic basins form widespread cover successions and are relatively undeformed.
