Abstract

As part of the National Geoscience Agreement with the Northern Territory Geological Survey, Geoscience Australia is evaluating the geological setting of the mafic-ultramafic intrusions in the Arunta Province. The major aims of this study are to constrain the various mafic-ultramafic magmatic systems within the event chronology of the Arunta, and to provide a geoscientific framework for assessing the resource potential of the intrusions. SHRIMP U-Pb geochronology results of thirteen mafic-ultramafic bodies have highligted the episodic emplacement of the Arunta intrusions during the Proterozoic. Five major magmatic events from 1810 Ma to 1130 Ma have been identified. Geochemical discrimination diagrams show that the Arunta intrusions fall into two major geochemical groups that highlight geographical differences in prospectivity for Ni-Cu and platinum-group element mineralisation.
