A multi-disciplinary approach for defining nickel and gold mineral systems in the Halls Creek Orogen, Western Australia

This PhD thesis presents a multi-scale and multi-disciplinary study for understanding nickel and gold mineral systems in the Halls Creek Orogen, Western Australia. Although a broad lithological framework for the study area was well-established, ambiguity regarding the tectonic evolution and contribution of geodynamics to the mineral system provoked this study. A range of geological investigation was conducted at different scales that include geodynamic numerical modelling, geophysical interpretation, and isotopic analyses. The research demonstrates a better understanding of geodynamics leads to greater understanding of large-scale controls on Paleoproterozoic mineral systems, which will result in better support for regional scale mineral prediction.
