This PhD project at Monash University investigates the physical mechanisms governing magmatic sulfide transport and ore formation, a process critical to the accumulation of valuable metals such as nickel, copper, cobalt, and platinum-group elements. Despite their economic significance, magmatic sulfide deposits constitute less than 1% of the host igneous systems, and the processes of sulfide migration, percolation, trapping, and textural development remain poorly understood.

The research will combine analogue laboratory experiments, high-resolution imaging, and geological interpretation to uncover how dense, immiscible sulfide liquids separate from silicate magma, migrate through crystal-rich mush, and accumulate into ore bodies. The project is closely integrated with theoretical and numerical modelling, offering a unique opportunity to work at the interface of geology, physics, and fluid dynamics.

Depending on the candidate’s background and interests, the PhD may focus on analogue experiments investigating percolation and migration of dense liquids through granular media, quantitative analysis of droplet size distributions and morphologies using X-ray CT imaging, comparison of experimental results with natural magmatic sulfide textures, geological interpretation at various scales, and development of physical criteria and textural indicators relevant to mineral exploration.

Experiments will be conducted in the Geodynamics Modelling Laboratory at Monash University, with access to advanced imaging facilities including medical and micro-CT, and potential synchrotron beamtime. The project is a collaboration with CSIRO Mineral Resources and involves supervisors from Monash University, CSIRO, University of Melbourne, and University of Cambridge. Principal supervisors are Associate Professor Anja Slim and Professor Alexander Cruden (Monash University), and Dr Margaux Le Vaillant (CSIRO).

The successful candidate will receive a full stipend (approximately AUD $37,000 per annum) and fees covered, open to any nationality. The award also includes single health cover for international students, a relocation allowance, and funds for travel to conferences, workshops, and visits to collaborators.

Applicants must have a First-class (H1 or equivalent) bachelor’s or master’s degree in geology, geophysics, geoscience, physics, engineering, or a related discipline. Strong interest in experimental geoscience, fluid dynamics, or physical modelling is required, along with willingness to work in a laboratory environment and engage with quantitative data analysis. Experience with image analysis, laboratory experiments, or physical modelling is desirable but not essential. Proof of English proficiency is required for candidates from countries where English is not the sole official language.

Applications are assessed on an ongoing basis until 23 March 2026. The preferred start date is the second half of 2026, but a later start is possible. Interested candidates should email [email protected] with a single PDF containing a cover letter, academic transcripts, and a brief CV. Shortlisted candidates will be invited for a Zoom interview.
