PhD Position – Fluid/Rock Interactions in Fault Zones (Hydrothermal Systems, Clay Minerals)

Summary
This PhD project focuses on fluid/rock interactions within fault zones of the Argentera-Mercantour massif. The objective is to characterize hydrothermal fluid circulations (both active and fossil) through the study of clay minerals, in order to better constrain pressure–temperature–time conditions and better understand the mechanisms involved in geothermal systems and ore-forming processes. The project relies on a multidisciplinary approach combining mineralogy, geochemistry, isotopic analyses, and numerical modeling.

Requirements / Profile
The selected candidate will join the “Geology of Mineral Resources” team at GeoRessources (UMR 7359), University of Lorraine, and collaborate with experts from partner laboratories.
We are looking for a highly motivated candidate with a strong interest in fluid circulation in fractured environments, mineralogy, and geochemistry. Experience or interest in numerical modeling and quantitative analysis of geological data will be appreciated.

How to apply
Applicants must submit the following documents:

• CV
• Cover letter
• One recommendation letter (from academic supervisor or internship mentor)
• Academic transcripts

Applications should be sent to Delphine Charpentier (delphine.charpentier@univ-lorraine.fr) before May 28, 2026.
An online application must also be submitted via the ADUM platform.
