Northern Territory Geological Regions 2500K

The Northern Territory is dominated by Palaeo- to Mesoproterozoic orogens and basins, with localised outcrop of Neoarchean (2.7-2.5 Ga) granite and gneiss. 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.
