This research was undertaken on the X-ray Fluorescence Microscopy beamline at the Australian Synchrotron, Victoria, Australia. The lead author acknowledges Ernie Nickel as an inspiring friend, colleague and fount of wisdom on nickel mineralogy, and also Ben Grguric for stimulating discussions of the complex Ni sulfide mineralogy of altered komatiites. We thank BHP-Billiton for access to diamond drill core from Betheno. Belinda Godel is funded by the CSIRO Office of the Chief Executive Postdoctoral Fellowship Program. Marco Fiorentini acknowledges financial support from the ARC through grant LP0776780. The synchrotron work would have been impossible without assistance from Robin Kirkham, David Paterson, Daryl Howard and Martin de Jonge. Norman Pearson and Kevin Grant are thanked for help with the electron microprobe. The electron microprobe data were obtained using instrumentation funded by ARC LIEF, and DEST, Systemic Infrastructure Grants, industry partners and Macquarie University. Dr Sarah Dare and Dr Chusi Li provided helpful and insightful reviews. This is contribution #707 from the Australian Research Council National Key Centre for the Geochemical Evolution and Metallogeny of Continents (URL:, and an output from the Minerals Down Under National Research Flagship.
