Job Description
Thesis Subject
At CNRS-ISTO, PhD Title : Artificial Intelligence supported hypothesis formulations on metal-rich granites: implications for critical metal prospectivity
Missions: Rare metals granites are small magmatic bodies that contain critical metals such as Li, Nb, Ta, W, Sn at concentration levels well exceeding the conventional granites. In Europe, granites and the related pegmatite rocks, constitute the main resources for these elements. Yet, no model can explain their genesis, why they are so rare and why they form such small magmatic bodies. With this project, we plan to use available solid-liquid-vapour partitioning data for these critical elements to simulate melting - crystallization -degassing processes operating in granitic magmas and train AI models under a large range of P-T-chemical conditions. The obtained numerical simulations will be compared to a large database of granite bulk rock compositions (major and trace elements and isotopes), which have been established by the associated partner BRGM, to provide hypothesis on the range of thermodynamic conditions that can potentially produce rare metal-rich granites.
Your Work Environment
The PhD project belongs to the REALISE MSCA Doctoral Network (https://realise-dn.eu/). The main part of the project will be carried out at the Institut des Sciences de la Terre d'Orléans (ISTO, France) and the secondments at the Katholieke Universiteit Leuven (KUL-Belgium) and the Bureau des Recherches Géologiques et Minières (BRGM-France).
Activities: By harvesting a large number of melting-crystallization-degassing data and simulations, we plan to: 1) provide unpreceded comprehensive constraints on the genesis of these magmatic geochemical anomalies and 2) propose a new generation of predictive models based on AI that could be used to search for new deposits. The results will be applied to French rare metal granites including the Beauvoir rare metal granite (Imerys kaolinite and Li deposit).
Competences: outstanding and highly motivated doctoral candidates are sought to work at the intersection of igneous petrology, machine learning, and societal applications. Recruited researchers may be of any nationality and they must not have resided or carried out their main activity (work, studies, etc.) in the France for more than 12 months in the 36 months immediately prior to the recruitment date.
