PhD Thesis Project
Paleomagnetic records from Australian lake sediments and their incorporation into geomagnetic field models commencing in 2023
Field location:Lakes in Victoria and Queensland, Australia
Sponsor: The PhD project is supported by a scholarship within the framework of an Australian Research Council (ARC) Discovery Early Career Research Award (DECRA) Project
Supervisors: This PhD Project would be supervised by Dr Agathe Lise-Pronovost (School of Geography, Earth and Atmospheric Sciences, the University of Melbourne) with co-supervision by Assoc. Prof. David Heslop (Australian National University) and Dr Monika Korte (GFZ, Germany).
Project: The objective of this project is to construct high quality records of Earth’s magnetic field over the last 10,000 years in Australia and integrate the new data into geomagnetic field models. The study sites are lakes known to contain reliable sedimentary paleomagnetic records and located in a critically under-documented region of the globe. The integration of Australian paleomagnetic data into the next generation of geomagnetic field models for the Holocene will importantly contribute to the international effort understanding Earth’s magnetic field evolution and future impact on society.
The PhD student will be involved with lake sediment coring, core opening and sampling, paleomagnetic analyses and geomagnetic field modelling. The student will be based in Melbourne and work as part of an international team with expertise in sedimentary magnetism and geomagnetic field modelling. The candidate will play a key role in constructing high-quality centennial-scale resolution paleomagnetic records from Australian lake sediments.
Skills required:We are looking for an enthusiastic and highly motivated student to undertake a PhD project in paleomagnetism. We would encourage students with a Honours or Masters research degree or equivalent in Earth Sciences, Geophysics or equivalent, to apply. It would be advantageous to have the following skills (or a strong interest in developing them): paleomagnetism, conducting laboratory experiments, programming, or related disciplines.
Support: The applicant will receive a full stipend (living allowance) of up to $33,000 per year (increased annually). All costs of the project are covered by funds from the Project. The scholarship includes visits to ANU in Canberra for paleomagnetic analyses, a 6-week's visit to GFZ (Germany) and participation to at least one international conference.
Research Environment: The University of Melbourne is a research-intensive university and the School of Geography, Earth and Atmospheric Sciences has an active program in key areas of Earth Sciences research. You will join a lively and collegial team of post-graduate students working on related projects.
How to apply? Applications will be reviewed from the 16th of December 2022. Applicants should submit 1) a cover letter, 2) a CV, 3) academic transcripts and 4) the names and contact details of two referees via email to Dr Agathe Lise-Pronovost (firstname.lastname@example.org).

Budj Bim Indigenous technology
The Budj Bim World Heritage Cultural Landscape is internationally recognised for preserving the world’s oldest aquaculture system, which provided an economic and social base for the Gunditjmara people of South-western Victoria for more than six millennia. What technologies were used by Gunditjmara people to carve canals in the volcanic landscape? Oral tradition suggests that fire was used to assist cracking, but empirical evidence is lacking. This project will use archaeomagnetic analysis to provide evidence for ancient fire technology.
With permission from the traditional owners, volcanic rock samples will be collected in and out the canals. Stepwise thermal demagnetisation will inform on the heating histories since the 40,000 years old Tyrendarra lava flow, including an evaluation of bushfire effect.
This project is part of a larger project led by Dr Martin Tomko (School of Engineering, The University of Melbourne) that aims to elucidate the engineering processes that enabled the Gunditjmara to site, plan, construct, operate and maintain this aquaculture complex, to show how it may have evolved over time, and how it responded to changing social and environmental circumstances. The student will conduct the magnetism experiments at the Australian Archaeomagnetism Laboratory at La Trobe University (Melbourne) in collaboration with Professor Andy Herries.

Archaeological science of natural mineral pigments and cultural heritage
While much of our knowledge of past societies is lost to time, we can use analytical approaches to cultural materials (natural mineral pigments -Fe-oxides and -hydroxides) to answer key archaeological science questions. These questions include research to characterise ancient technologies and to understand cultural exchange of materials. As part of an ARC Discovery Project, we are developing a suite of sophisticated and non-destructive techniques, some based in geochemical methods, toward the chemical and physical characterisation of complex materials such as natural mineral pigments, resins and binders.
Aspects of the project include elemental, mass spectrometric, microbial DNA and spectroscopic techniques. Opportunities include characterisation of binders in cultural heritage objects (py-GC-MS and IR spectroscopy) and material and pigment analysis by X-ray and spectroscopic methods. Collaborators include scientists at the University of Melbourne, Flinders University, archaeologists at Flinders University and Indigenous community partners.

The megalithic jar sites of Laos
Laos is home to one of Southeast Asia’s most mysterious archaeological cultures. The ‘Plain of Jars’ is a megalithic landscape, comprising more than 2,500 hollowed, stone jars, discs, and boulder burial-markers, spread over more than 120 documented sites, 11 of which were inscribed as UNESCO World Heritage in 2019 (www.plain-of-jars.org). The jars vary in height from 1 to 3m and are placed alone or in groups numbering several hundred. They appear to be part of a complex burial ritual and were transported from quarries several km away.
This Honours project focusses on petrographic/geochemical characterisation of the various jar materials and of samples from potential sources. Thin sections of the samples, prepared either locally or commercially, will be examined using the petrographic microscope, electron microscopy (SEM-BSE imaging) and the electron microprobe. Microscopic observations will establish the mineralogy and texture of the rocks, while SEM imaging will provide mineralogical and intergrowth detail at the sub-microscopic scale, as well as mineral identification via SEM-EDS analysis. Electron microprobe analyses will be used to obtain quantitative mineral chemical compositions which – together with the mineralogy and textures – can be used to support potential matches with source materials. Additional instrumental techniques may also be utilised (e.g. XRF and ICP-MS to obtain major/trace element abundances in whole rocks; laser ablation ICP-MS to obtain trace element concentrations at 0.1 mm scales; isotopic analyses of strontium and neodymium).
This project would best suit a recent geology/mineralogy graduate with an interest in petrography, mineralogy and analytical geochemical techniques. All analytical equipment (except for XRF) is available within SGEAS.
