Metal Earth Postdoctoral Fellow Position

The first francophone university in North America, Universite 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.

With CAD $104 million in funding provided by the Canada First Research Excellence Fund and through strategic partnerships led by Laurentian University, with 4 Canadian universities, 6 government geological surveys and 3 international research centres, Metal Earth is the largest ever mineral exploration research project undertaken in Canada.

We seek applicants for 2 PDF positions:

1) Dating and sources of auriferous fluids along the Larder-Kirkland segment. The Metal Earth team has determined the age of gold mineralization and source of sulfur in the Val-d'Or vein field. There is a difference in the regional H-O isotope composition between the eastern (Vald'Or) and western (Larder-Kirkland) parts of the Cadillac-Larder Lake Fault zone which raises the question about the timing of auriferous fluid flow and source of sulfur in the gold deposits of the western segment. Objectives: 1) date by U-Pb monazite and xenotime that are coeval with gold deposition events; 2) assess the source of sulfur in sulfides coeval with gold using in situ multiple sulfur isotopes.

2) The Grenville Front east of Val-d'Or: a window into the Superior middle-lower crust. The Metal Earth team has shown negative Δ33S values in gold-related sulfides in Val-d'Or orogenic gold veins, which indicate a derivation of S from Archean volcanic rocks, in contrast to the positive Δ33S values of gold deposits in sedimentary rocks of the Abitibi (Canadian Malartic). The Grenville Front east of Val-d'Or contains Neoarchean high grade metamorphic rocks with minimal Grenvillian overprint, offering a rare window in the lower crust of the Val-d'Or vein field. Objectives: 1) date peak metamorphism; 2) determine P-T conditions of peak metamorphism; 3) estimate depletion is gold and associated elements in various grade metamorphic rocks; 4) estimate the composition of fluids and sulfur produced during prograde metamorphism.

The PDF will contribute to supervision of graduate students, within a team integrated with other researchers of the Metal Earth program. The research will include field and laboratory work. The PDF candidates must hold a PhD since a maximum of 3 years at the start of the position. Experience in Archean terrane geology, and strong fundamental and laboratory expertise are required in areas specific for each PDF position. The 2-year positions will start as soon as possible.

Salary will be determined according to the collective agreement in place at the time of hire. Salary range is from $50 000 to $75 000 per year plus benefits.

Candidates should prepare a complete candidacy package which includes: (1) a long-form CV that includes publications and research achievements, (2) academic transcripts, (3) 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 September 30, 2023.
