Australia's Large Igneous Provinces (LIPs) span almost the entire Earth's geological history, ranging from Early Archean to Recent. LIPs in continental Australia are represented by continental flood basalts, fragments of oceanic plateaux, volcanic ri

Australia's nickel sulfide industry has had a fluctuating history since the discovery in 1966 of massive sulfides at Kambalda in the Eastern Goldfields of Western Australia. Periods of buoyant nickel prices and high demand, speculative exploration, a

Proterozoic mafic–ultramafic intrusions of the Arunta Region record a protracted period of magmatism during the evolution of this geologically complex and tectonically long-lived terrane in central Australia. New U–Pb zircon geochronology data hi

The Arunta Region in central Australia records multiple Proterozoic crustal processes over a 1500-million-year period. The timing of mafic–ultramafic magmatism in this evolution is constrained by SHRIMP U–Pb dating of zircon, which is a primary p

A number of Paleoproterozoic layered mafic-ultramafic intrusions in the central part of the Halls Creek orogen of East Kimberley, Western Australia, have been explored for platinum group elements, chromium, nickel, copper, cobalt, and gold. Here we r
