As Director of MERC and Metal Earth, I'm pleased to present our Spring 2023 newsletter, featuring a new data location map from the Chibougamau Transect, research updates, events and courses, featured publications, and career opportunities. We invite you to share our news with colleagues and would appreciate your feedback.

CHIBOUGAMAU TRANSECT DATA MAP
|
|
|
The Chibougamau Transect data location map is now available on the Metal Earth Hub, including sample stations and links to source data.
This map and data provide a complete picture of the transect's geophysics, geochemistry, and geochronology.
The data release includes a location map, gravity and MT station coordinates, magnetic susceptibility measurements, outcrop photographs, lithological and structural data, and geochemistry sample data and locations.
Data was collected by the Université du Québec à Chicoutimi during the 2017-2020 field seasons. Lucie Mathieu (UQAC) was the lead researcher on the Metal Earth Chibougamau Transect. The map was compiled by Anne Barr and Pouran Behnia.

METAL EARTH RESEARCH UPDATES
|
|
|
Researchers shared updates and plans in March at the Metal Earth Scientific Meetings in Toronto. Recordings of these presentations have been added to the Metal Earth YouTube playlist. A few videos have not been shared to protect data/information. If you'd like the stay up to date or hear the latest project updates from researchers, this is one channel to watch!

METAL EARTH GAINS NEW POST-DOCTORAL FELLOW
MERC is pleased to welcome a new post-doctoral fellow/research associate with Metal Earth. Jacob Strong has a BSc and MSc from McMaster University and a PhD from Monash University in Melbourne, Australia. His background is in isotope geology with PhD work on gneiss domes in the Winnipeg River terrane. Strong will apply his skills to Lu/Hf in zircons examining the North Caribou Terrane in the Superior Craton, following on from isotopic mapping of the Abitibi and Wawa subprovinces earlier in the project.

PDAC-SEG Student Minerals Colloquium
The 14th Annual PDAC-SEG Student Minerals Colloquium (SMC) featured more than 70 posters on a range of topics worldwide.
|
|
|
|
Winners were selected by volunteer industry judges and awarded prizes at a reception during the Convention. Laurentian University MERC/Metal Earth student Julian Melo-Gomez was recognized on the podium at the MSc level for his poster Using gold to explore for gold: Trace element content of native gold across Ontario. Metal Earth student Rhian Dentelbeck (University of Ottawa) also made the podium. All student abstracts, winners, and winning posters are posted on the SMC website. Organizers would like to thank the competitors, judges, and sponsors for their support.

SHORT COURSE PRESENTATIONS ONLINE

New geophysical and geological insights into how crustal architecture influences the gold and base metal endowment of Precambrian terranes
In March 2023, MERC led a sold-out Short Course at PDAC. The presentations are now available for download.
The course included presentations from key researchers (geologists, geophysicists and data analytics) on the integration of geophysical, geological and mineral deposit data to understand the subsurface architecture, including examples from the most important mining camps in Ontario and Quebec.
These presentations contain new research and analysis from Laurentian University’s Metal Earth project, which generated more than 1,000 km of reflection seismic, magnetotelluric and gravity surveys that have provided some of the highest resolution imaging across 13 transects with differing mineral endowment in granite-greenstone terranes of the Superior and Southern provinces. The results highlight crustal architecture and metallogeny derived through the integration of geophysical studies at detailed and regional scales integrated with geological, geochemical and geochronological data.

GAC-MAC-SGA ANNUAL MEETING
|
|
Discovering Ancient to Modern Earth
Laurentian University's Harquail School of Earth Sciences is hosting the Annual Meeting of the Geological Association of Canada, Mineralogical Association of Canada, and the Society for Geology Applied to Mineral Deposits (GAC-MAC-SGA) from May 23-31.
More than 500 geologists from across the globe will participate in three days of scientific presentations and six days of field trips and workshops, including symposia on Critical Minerals and Sudbury Geology, special sessions on Environmental Aspects of Mine Wastes, Geoscience Communication, and a wide range of other geoscientific topics. The Program also includes special events on Indigenous Relations, Women in the Geosciences, and the Arctic. Delivered in hybrid format with on-site and virtual components, conference abstracts, talks, and posters will be given in English or French.

Structure, Tectonics, and Mineral Exploration
LATE AUGUST TO EARLY SEPTEMBER 2023
This 8-day field- and lecture-based course addresses the fundamentals of structural field analysis. Fieldwork will be done in Sudbury, Ontario, which is located at the junction between the Archean Superior craton, the Paleoproterozoic Southern Province, and Mesoproterozoic Grenville Province, allowing easy access to a variety of geological environments from granite-greenstone belts, to continental rift sequences, to high-temperature gneissic terranes. Mapping exercises will be complemented by lectures, allowing the unique opportunity to directly apply classroom learning to the field.
By the end of the course, participants will have learned how to:
- conduct a geometrical structural analysis of a multiply deformed terrane
- complete a structural interpretation of a deformed terrrane
- determine the sense of movement in shear zones
- determine the geometry and dynamic significance of quartz vein systems.
