PhD Position: Cycling of elements in flooded abandoned ore mines in Quebec (Canada)
Research project on the structural and hydrothermal evolution of gold mineralization at the Casa Berardi mine, Abitibi, Québec
Fully-funded PhD position in hydrogeochemistry at UQAM (Québec, Montréal)
In the province of Quebec (Canada), many ore mines have been exploited to extract minerals. After exploitation the mines are abandoned and become flooded with groundwater. These heavily disturbed subsurface habitats host a whole new microbial community, which will colonize these abandoned and isolated sites, adapt and evolve. In such closed environments, organisms can only rely on recycling elements already present and have to locally adjust to elevated concentrations of heavy metals and organic contaminants (e.g., fuel leaking from the tank of abandoned machinery).
The goal of this PhD project is to understand the cycling of elements and biogeochemical processes occurring in abandoned ore mine ecosystems in relation to depth and the presence of contaminants.
This thesis will rely on concentration measurements and multi-element isotopic approaches such as compound-specific isotope analysis of organic and inorganic compounds. The project includes analytical method development, laboratory and field work. The chosen candidate will work in close collaboration with two other PhD students and with a team of professional divers.
The PhD position is based at UQAM under the supervision of Prof. V. Ponsin (Earth Sciences Department, https://scta.uqam.ca) and co-supervision of Prof. C. Lazar (Biology Department, https://bio.uqam.ca). The PhD candidate will be a member of the research centre Geotop (https://www.geotop.ca/index.php/fr) which provides a highly comprehensive and dynamic work environment by offering many possibilities to access funding, equipment and methods, courses and seminars on Earth's dynamics.
