Geodynamic controls on critical-mineral fertility

Last updated: August 2026

About

Critical-mineral systems form where tectonic setting, mantle sources, melting, volatile transport, and lithospheric structure combine in favourable ways. Surface correlations can identify patterns, but they do not by themselves explain the deep-Earth processes that created those conditions.

This project will use plate reconstructions and time-dependent mantle-convection models to investigate how fertile mineral-forming environments evolved through deep time. It will identify combinations of subduction geometry, mantle flow, melting, and lithospheric structure that can be tested against the age and location of known mineral systems.

Research questions

• Which geodynamic conditions favour fertile magmatism and mineral-system formation?
• How do supercontinent cycles, subduction, plumes, and lithospheric architecture alter those conditions?
• Can models distinguish physical controls from apparent correlations in the geological record?

Methods and data

Projects can combine plate reconstructions, mantle-convection simulations, mineral-deposit datasets, geological maps, geochemistry, and uncertainty analysis. The work can begin globally and then focus on an Australian province or a particular commodity.

Possible projects

Possible directions include mapping fertile tectonic settings through time, tracking subducted material in convection models, or comparing predicted geodynamic indicators with a copper, rare-earth, or other critical-mineral dataset.

Essential background

Useful preparation includes geology, geophysics, geochemistry, data science, physics, programming, or numerical modelling.
