n/a (phone)
Dr Sheree Armistead is a Postdoctoral Research Fellow at CODES (Centre for Ore Deposit and Earth Sciences). Her research focuses on the links between plate tectonics and mineral systems, and the cyclical and secular changes of these throughout Earth’s history. Sheree primarily uses isotope geochemistry, data science, GIS and plate reconstructions in her research.
Biography
After completing a BSc (Honours) at Monash University, Sheree worked at Geoscience Australia as a Geochronologist and Mineral Systems Geologist. She subsequently completed a PhD at the University of Adelaide in 2019 on the tectonic evolution of supercontinent Gondwana, focusing on Madagascar. She used isotope geochemistry, structural geology and geodata analytics to constrain the paleogeography of Madagascar and (paleo) neighbouring regions throughout several supercontinent cycles. This research helped to constrain plate reconstructions for the entire Earth over the last billion years.
Sheree then undertook a two-year Postdoctoral Research Fellowship at the Geological Survey of Canada in Ottawa, which was funded through the Metal Earth programme at Laurentian University. This project used a global database of Pb isotopes from ore deposits to understand early Earth geodynamics and plate tectonics, as well as implications for ore-forming regions, particularly the Superior Province in Canada.
In 2022, Sheree joined the University of Tasmania as a Lecturer in Marine Geoscience and Postdoctoral Researcher at IMAS (Institute for Marine and Antarctic Studies). Since June 2022, Sheree has been a Postdoctoral Researcher at CODES, working on a collaborative project with Geoscience Australia to understand the tectonic and metallogenic evolution of western Tasmania.

- Description
- The exact timing of mineralisation and ore deposits formation are difficult to constrain accurately, as these deposits tend to be affected by multiple episodes of deformation and crystallisation. New techniques currently being developed now make the dating of at least some of these deposits possible. This project will use these techniques to constrain the timing of mineral growth some of the most problematic deposit in Tasmania, eastern and northern Australia to better characterise existing deposit and help with exploration for new ore resources.

- Description
- This project will involve the compilation of Pb isotope data from ore minerals, which will be added to the established DepIsodatabase. These data will then be used to understand the spatial and temporal patterns of Pb isotopes in many terranes around the world. Pb isotopeanomalies have been recognised in the modern mantle through the analysis of various oceanic basalts, however their origin remains poorlyunderstood. We seek to understand the Pb isotope signatures of ancient (Archean and Proterozoic) mantle and crust, to understand how the evolutionof plate tectonics has occurred on Earth and whether these ancient signatures influence modern oceanic basalts. We will develop an R package fordealing with the complicated calculations required for transforming and interpreting Pb isotope data, which will assist the community in using Pbisotope data in a consistent and transparent way.
