Postdoctoral researcher (f_m_x) - Reactive Transport Modelling of Sediment Hosted Base Metal Deposits Reference Number 6192

New sources of strategic metals such as copper and zinc are required to facilitate the energy transition. Some of the highest value base metal resources are hosted by fine-grained siliciclastic (± carbonate) rocks. Many genetic models for these deposits suggest that ore stage sulfide minerals form via mineral replacement reactions, which requires the movement of low temperature (< 300 ºC) fluids through fine-grained siliciclastic host rocks. The pore space in these units is complex, due to a combination of depositional and diagenetic processes. In sediment hosted mineral systems, we need to fully characterize pore scale mineralogical processes to understand how non-linear feedbacks result in mass fluxes that are capable of producing ore grade mineralization. In this project we will seek to simulate key processes with input data from field and lab-based projects on Zn and Cu deposits in Australia, Canada and Germany.

This project will be a joint initiative of GFZ's Section 3.1 - "Inorganic and Isotope Geochemistry" (Prof. Dr. S. Gleeson, Dr. Joe Magnall) and Section 3.4 “Fluid Systems Modelling(Prof. Dr. Michael Kühn). It will contribute to the Helmholtz Association's program oriented funding scheme under Topic 8 "Georesources for the Energy Transition and a High-Tech Society".
