3- year PhD position ISO2CARE: Silicate weathering as CO2 sinkatInstitute of Applied Geosciences TU Graz (Austria)FWF-Project Start 01. 10. 2025: Details & application through (Deadline 15. 10. 2025): https: //jobs. tugraz. at/de/jobs/c08579e4-5aa6-7e51-b4e6-6877cd6f99f5The project aims to elucidate the fundamental processes and kinetics of silicate weathering using Si isotopes as tracers. It seeks to understand how parameters such as temperature, pH, pCO2, Si concentration, and organic ligands affect kinetic and equilibrium Si isotope fractionation during the dissolution and formation of amorphous Si phases.
A main goal is to determine how changes in these parameters impact reaction products and isotope exchange kinetics. By combining experimental and theoretical approaches with a proof of concept in natural settings, the project aims to assess Si isotope compositions to evaluate silicate weathering and CO2consumption. This research is crucial for understanding and predicting weathering processes and their role in the global carbon cycle, especially in the context of climate change and potential carbon sequestration strategies. Responsibilities- Design of experimental studies on amorphous silicon phases and their transformation(FWF-Project https: //online. tugraz. at/tug_online/fdb_detail.
ansicht?cvfanr=F57636&cvorgnr=2387&sprache=2)- Development and execution of experimental setups and systematic experimental series in temperature ranges from -10°C to 90°C- Chemical and mineralogical characterization of experimental products (solid/liquid phases)- Isotope geochemical analyses of various stable isotope systems, particularly silicon (Si), but also elements such as iron and oxygen- Interpretation of results in respect to the above aims considering geochemical modelling tools and being active in preparation of manuscripts - Presentation of results at workshops and conferences- Participation in selected teaching activities- Co-supervision of Bachelor's and Master's thesesDesired Qualification- We are looking for highly motivated researchers with a strong interest in experimental and analytical geochemistry, particularly in stable isotope geochemistry, and a genuine enthusiasm for laboratory work.
- Experience in mineralogical/geochemical analysis and experimental methods is an advantage. - Previous experience in a clean room laboratory is desirable but not required.
