Postdoctoral Fellow : Sulfur cycling during mountain building events through time

The first francophone university in North America, Université Laval is amongst the top-ranked comprehensive universities in Canada. Recognised for its leadership and high achievements in education and research, it offers a convivial and diverse environment in the heart of Quebec City, a UNESCO World Heritage City. The university community counts amongst its ranks over 45,000 students and offers an engaging work environment which was recently ranked by Forbes magazine as one of Canada's best employers.

Project description:

This project seeks to understand the secular evolution through time of sulfur cycling at craton margins by tracing supracrustal multiple sulfur isotope signatures to tectono-magmatically characterised plutonic suites. We have ongoing boots-on-the-ground projects in various orogens within and bordering on the Superior craton including the Archean Pontiac subprovince and Baie James regions of the Superior Craton, the Paleoproterozoic Ungava Orogen and Southeast Churchill, and the Mesoproterozoic Grenville orogen.

This project will necessitate fieldwork in some of the above locations to collect suites of samples, and data compilation and selection of historic samples in others. Lab work will include running our in-house acid reduction sulfur extraction line to prepare samples for multiple sulfur isotopes analyses. These analyses will be completed at IGP Paris by fluorination line - IRMS. The candidate will also be able to utilize our LA-ICPMS-(QQQ) for which we have developed δ34S analyses.

Working environment:

The candidate will work directly with Prof LaFlamme, Canada Research Chair in Sulfur isotope geochemistry, as well as be integrated within the Chair in Mineral Exploration Research Group led by Profs Georges Beaudoin, Bertrand Rottier, Carl Guilmette and Crystal LaFlamme. This research group is composed of research professionals, postdocs, PhD, MSc and honours' candidates and represents about 45 people studying the fields of geodynamics, geochemistry, ore deposit geology as related to mineral exploration. The PDF will contribute to the training of graduate students and have the opportunity to be involved in collaborative research within this group. Within Université Laval's department of geology and geological engineering, the PDF will have access to the wide-ranging sample preparation and micro-analytical equipment of the MicroLab, including a microprobe, SEM, microXRF, XRD, LA-ICPMS (QQQ), and NIR-optimized fluid inclusion laboratory.

Salary will be determined according to the collective bargaining agreement in place at the time of hire, and is around $50,000/ year + benefits. The position is for 2 years with the possibility to extend for a third. The candidate must have a PhD degree awarded not more than 3 years ago.

How to apply:

Candidates should prepare a complete candidacy package which includes: (1) a long-form CV that includes publications and research achievements, (2) academic transcripts (unofficial is ok), (3) 1 page letter of motivation, (4) names and contact details of three references.

The full application package should be sent electronically as a PDF document to

Applications will be accepted until December 15, 2023.

Université Laval, through its commitment to the promotion of diversity, invites all qualified applicants to submit their candidacy. In particular, we invite women, members of visible minorities, members of ethnic or indigenous groups and differently-abled people to submit their candidacy. Priority will be given to those who are Canadian citizens or who are permanent residents of Canada.
