PhD Opportunity – Phase Change and Reactive Models of Ore Deposition

This PhD investigates how fluid flow, phase change, chemical reactions and transient structural processes drive ore deposition in geothermal and orogenic systems. Using numerical reservoir simulation, you will model two‑phase flow, heat and mass transfer, supersaturation, and permeability changes caused by coseismic dilation or pressure cycling. The research spans epithermal environments, deep orogenic gold systems, and a New Zealand case study to quantify ore accumulation rates, favourable parameter regimes, and structural controls on mineralisation. The project suits a candidate with strong numerical and computational modelling skills, familiarity with fluid flow or geothermal processes, and confidence working with geological, geochemical, and structural datasets. Analytical thinking and interdisciplinary collaboration are essential. Supervisory Team You’ll be supported by a multidisciplinary team with expertise in structural geology, numerical modelling, and mineral systems: Dr. Michael Gravatt, Prof. JR Rowland, Dr. Ayrton Hamilton and Prof. David Dempsey (University of Canterbury) Who Should Apply This project is ideal for students with backgrounds in: Numerical modelling or Applied mathematics with an interest in Earth science, Fluid mechanics, Structural geology or Geophysics with a strong analytical background. Funding This project is funded by the MBIE Endeavour Research Program “Next Generation Ore (N-GO)” and will involve working with a wider team across Aotearoa – particularly with University of Canterbury. The stipend will be $35,729 (Year 1), $36,467 (Year 2), $37,146 (Year 3). The scholarship will also cover fees and health insurance (for international students only).
