About the Project

Recent analytical developments in trace element geochemistry have made it possible to accurately analyse the fractionation of germanium from silicon during partial melting of rocks and in igneous crystal fractionation series. This project will use a new analytical method to analyse Ge in minerals and so track which rocks and mineral assemblages are involved in fractionating Ge from Si. The method is expected to highlight igneous systems that are driven by the melting or fractionation of hydrous minerals (amphibole, mica), garnet and feldspars. There is an option to combine the analytical work with experiments that measure the distribution of germanium between minerals and melts.

Our Department has a strong tradition in microbeam mineral and rock analysis (EMPA, SEM, Laser-ICP-MS) and a newly expanded high-pressure experimental laboratory. We emphasize cross-links between geochemistry, petrology and geophysics in mantle and lithosphere studies.
We seek outstanding students to actively contribute to a team effort in the Australian Laureate project “Deep Earth Cycles of Carbon, Water and Nitrogen” (
Direct entry into the PhD programme at Macquarie requires completion of a two-year Masters degree with a major research component at Distinction level (75%). For applicants with an Honours or shorter Masters degree, there are also MRES/PhD package scholarships which enable completion of MRES as a training pathway to a Doctoral degree.
International scholarships include living stipend and fees for 3 years. Applications are now open: application deadline is July 31st.
There is also an option for co-tutelle projects with partner universities.
You are encouraged to discuss a research proposal before completing your on-line application. Informal enquiries should be addressed to Prof. Stephen Foley ([Email Address Removed]) or Prof Olivier Alard ([Email Address Removed]). We also encourage students to suggest their own research themes. Enquiries about openings further into the future are also welcome.
