PhD Opportunity : Squeeze-Box Modelling of Structural Permeability and Ore Focusing

Mineral systems rely on a “metal transfer superhighway” that moves fluids from deep in the crust to shallow levels where ore deposits can form. Structural permeability—damage, fractures, and fault networks—controls these pathways. Yet we still lack a clear understanding of how permeability develops, how it varies across scales, and how it focuses mineralisation. This PhD will use advanced finite element modelling to simulate fault slip, stress accumulation, and damage formation in 3D “squeeze-box” experiments. You’ll explore how tectonic forces interact with real geological structures to create zones of enhanced permeability that may host mineral deposits. 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: Structural geology, Geophysics, Geomechanics, Numerical modelling, Earth science with strong quantitative skills. Experience with finite element modelling or coding is beneficial but not essential—enthusiasm and curiosity matter most. 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).
