Reconciliating the metamorphic record with the tectonic setting during the emplacement of rare-earth element rich alkaline intrusions in the Grenville Province

  • Master
  • Fall
  • Summer
  • With scholarship


Research project description

Alkaline magmatic intrusions in the Grenville Province represent a potential source of rare earth elements (REE) in Quebec, but the tectonic setting and geological processes that led to their formation are debated. The candidate will address apparent geodynamic contradictions between tectonic settings inferred from geochemical and isotopic data and from limited metamorphic constraints during the emplacement of REE-rich alkaline intrusions. To do so, the candidate will acquire robust constraints on the timing and pressure-temperature conditions of metamorphism in the country rocks hosting REE-rich alkaline intrusions in the Haut-Saint-Maurice area. Research will involve a combination of fieldwork, detailed petrography, thermobarometry and/or phase equilibrium modelling, and various petrochronological approaches depending on the suitability of the country rocks (e.g., in-situ U-Pb on monazite, xenotime, zircon or titanite; Lu-Hf on garnet).


Starting date

Fall 2022
With possibility of conducting fieldwork during the summer. Qualified candidates are encouraged to apply even if they are only available in 2023.


Supervisor

Renaud Soucy La Roche


Required qualifications

  • Undergraduate degree (B.Sc.) in Earth sciences, geological engineering or equivalent
  • Fieldwork experience, ideally with deformed metamorphic rocks
  • Strong interest in metamorphic petrology and geochronology
  • Bilingualism (French, English) is an asset


Funding

INRS guarantees financial support to all students. A two-year scholarship (six semesters) funded by the Fonds de Recherche du Québec – Nature et Technologies is available for this project.

Commitment to equity, diversity and inclusion

Professor Soucy La Roche encourages all qualified individuals to apply, especially women, members of visible and ethnic minorities, Indigenous Peoples, persons with disabilities, members of LGBTQ2+ communities or others who identify with socially and/or economically marginalized groups. Special circumstances and non-traditional backgrounds will be considered in the evaluation of applications. Professor Soucy La Roche is committed to supervising the candidate in the language of their choice (English or French) to overcome language barriers and to encourage their inclusion in the research team. If needed, French courses are offered free of charge to facilitate integration into the INRS and Quebec City communities.
