Integrated U-Pb geochronology and palaeomagnetic studies of the Mundine Well dyke swarm (MDS) of the Pilbara Craton, Western Australia, are employed to test the hypothesis that Australia and Laurentia were joined as part of the Rodinia supercontinent. Ion microprobe U-Pb dating of zircon and baddeleyite indicates that the MDS was emplaced at 755+/-3Ma (95% confidence interval) and palaeomagnetic results...
Ion microprobe U-Th-Pb analyses of baddeleyite and zircon yield precise estimates of the age of Neoproterozoic mafic magmatism associated with initial rifting in the Adelaide Geosyncline and adjacent platforms in southern and central Australia. An age of 827 ± 6 Ma is inferred for emplacement of the Gairdner Dyke Swarm (GDS), based on 137 207 Pb/ 206 Pb analyses...
