TypeFull timeLevelStudent / Graduate / Internship22000 € / Year, Scholarship is AUD$35,000 p.a.Required educationMaster31 August 2024PostedA fully funded 3.5-year PhD project in igneous petrology and geochemistry has opened at the Earth Dynamics Research Group (https://geodynamics.curtin.edu.au ) as part of an Australian Research Council Discovery Future Fellowship project "Linking the deep carbon cycles with critical mineral deposits".Project backgroundThe current consensus is that carbonatites are produced by low-degree partial melting of the Earth's mantle, but not the usual mantle. Experimental, geochemical, and isotopic studies suggest that the lithospheric mantle is the source of carbonatite, but it must be fertilised in a particular way by CO2-rich fluids or magmas, the so-called carbonate metasomatism. Carbonate metasomatism has been reported in many mantle rocks of various tectonic environments, making it a ubiquitous process that plays a critical role in modifying the mineralogy and geochemistry (enrichment in CO2 and
REE ) of the lithospheric mantle, but carbonatites remain paradoxically rare. In other words, we have a conundrum: carbonatites are all sourced from the carbon-rich mantle, but not all carbon-rich mantle can produce carbonatites.Your work will involve applying state-of-the-art geochemistry and isotopic analyses techniques (whole-rock and in-situ radiogenic and non-traditional stable isotopes) on carbonatite and mantle xenoliths to decipher the link between the deep carbon cycle, carbonate metasomatism and mantle enrichments in the concentrations necessary to produce the critical ore carrier.Fieldwork is planned for East Africa, France, and other places deemed necessary for the project.This project will contribute to a federally funded research project that aims to decipher the first order mechanisms that control
REE
enrichment in the lithosphere and CO2-rich magmas. You will be given the opportunity to contribute and learn from other projects led by team member of the Earth Dynamics Research Group.This project provides a living stipend of AU$35,000 p.a. pro rata indexed, based on full-time studies, for up to a maximum of 3.5 years. International students will receive a 100% fee offset for up to 4 years. Support for fieldwork, analytical time, travel, conference attendances and publications will be fully covered by the scholarship.How to applyMust have a BSc Hons (first class) or Masters (by research) in geoscience (ideally related to geochemistry / isotope geology, igneous petrology or geochronology) by the time of appointment.We expect a solid background in geological processes and igneous petrology and/or geochemistry and isotope geochemistry (in-situ analyses expertise is especially valuable).The candidate requires the ability to work both independently and with a broad range of people from diverse backgrounds, as well as evidence of strong oral and written scientific English language competencies.The candidate requires a demonstrated commitment to publish results in scientific journals. Evidence of research experience, academic awards/publications/presentations at conferences is desirable.The deadline for complete applications (note specific requirements of endorsements on the scholarships webpage) is
31 August 2024
(Western Australia time,
UTC +8). The PhD may be started as soon as practicable, but we recognise arranging visas and travel may impact this (where relevant).Email applications with the email titled " FT23_PhD " to ****** .Applications should contain a 2- to 3-page CV and a 1-page motivation statement, together in a single pdf,labelled "Lastname_FirstName_ FT23PhD.pdf".Applications failing to use the correct email title, or provide incomplete documents may not be considered.Shortlisted applicants will have an online interview invitation by 15 September 2023. If you have not heard from us by then, your application was unsuccessful.Recommended applicants will be provided with further information on the PhD enrolment process at Curtin University (including upload of certified transcripts and demonstration of English language requirements).
