About the Project

Alkaline incipient melts produced by melting at 100-200km depth beneath continents carry dissolved H2O and CO2 into the shallower mantle where they solidify, modifying the sources of later volcanic melts. However, little is known about the mineralogy of the rocks they produce when they interact with the mantle at 60-120km depth, although these rocks form an important reservoir for H2O and CO2 in the mantle over time. This project will use novel experimental equipment with extra cooling to investigate the mineralogy of these metasomatic reaction products and the control they have on many trace elements.

Our Department has a newly expanded high-pressure experimental laboratory and a strong tradition in microbeam mineral and rock analysis (EMPA, SEM, Laser-ICP-MS). 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” (https://bit.ly/2Z6zZ4U).

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]). We also encourage students to suggest their own research themes. Enquiries about openings further into the future are also welcome.
