Special Sessions

SS01 - Advancements in Canadian Deep-Water Research, Chairs: Lilian Navarro (, Vittorio Maselli (, Elisabeth Steel (

Continental slopes and deep-sea basins not only host the majority of our energy reserves, but are also the loci of important geohazards such as submarine landslides, which can affect coastal communities. These basins have also become the target for the exploration of minerals that are critical for the energy transition. Numerous high-quality oceanographic, geophysical, and sedimentological studies along the continental slope and deep-water seafloors in Canada and worldwide, and high-resolution observations from outcropping deep-water rock sequences, have resulted in increased knowledge of deep-water processes and related deposits.

SS02 - Advances in Isotope Science: Methods and Applications of Non-Traditional Isotopes, Chairs: James Kidder (, Matthew Leybourne (, Daniel Layton-Matthews (

Non-traditional stable isotopes have been increasingly used to study the fluxes among the Earth's major reservoirs and through the geological record. Our knowledge of isotope fractionation mechanisms and controls during chemical transport and deposition in these emerging stable isotope systems has grown in recent years. In this session we aim to select a diverse series of contributions from analytical method development and analysis through novel applications of non-traditional isotope geochemistry that tracks element migration and cycling between the Earth's geosphere, biosphere, and hydrosphere.

SS03 - Advances in Marine Geology and Geodynamics and their Application to Understanding Ancient Metallogenic Terranes, Chairs: Erin Bethell (, Chris Galley (, Alan Baxter (, Mark Hannington (

The present-day oceans provide a natural laboratory to observe the structural, kinematic and magmatic history of oceanic and arc crust, which comprise a significant proportion of greenstone belts and accreted terranes. This session will highlight studies using modern marine geophysical and acoustic datasets to understand the tectonic evolution of different domains of oceanic and arc crust. We invite contributions that use these datasets to advance our knowledge of marine geological processes and apply what is learned to ancient metallogenic greenstone belts and accreted terranes. This session is a contribution to the CFREF Metal Earth and NSERC iMAGE-CREATE programs.

SS04 - Advances in the Study of Accretionary Tectonics in the Paleozoic: From the Appalachians to Zagros, Chairs: Deanne van Rooyen et al. (

This session seeks contributions on Paleozoic orogenic belts specifically focused on their evolution through time, with a particular emphasis on comparative work between different areas, either within a specific orogenic belt or among different orogens. We look forward to welcoming contributions dealing with a wide range of orogenic belts worldwide.

SS05 - Advances in VMS Deposits: Genetic Models and Approaches to Mineral Exploration, Chairs: Frank Santaguida (, Harold Gibson (

Volcanogenic massive sulfide deposits are among an economically important class of mineralization types globally. For example, VMS deposits currently account for over 16% of current world zinc production. The understanding of the genesis of these types of deposits continues to improve, resulting in successful approaches to exploring for new Zn-Pb-Cu-Ag-Au resources. The geodynamic setting of VMS deposits and the new technology that impacts mineral exploration will be discussed as invited keynote talks as well as more focused presentations. Topics will include predictive mapping/data modelling, geochemical signatures to host volcanic rocks, recent discoveries, and emerging terranes.

SS06 - All that Glitters is Cold: Advances in Quaternary Glacial Investigations, Chairs: Jessey Rice (, Tyler Hodder (, Riley Mulligan (

Our understanding of ice sheet dynamics, evolution, and sedimentary environments remains incomplete, despite its importance in identifying and managing groundwater and aggregate resources, the evaluation of potential geohazards, and facilitating drift prospecting efforts. This session welcomes submissions describing recent or ongoing investigations of modern to ancient glacial systems at regional, local or micro-scales that are guided by detailed fieldwork, lab analyses, geophysical and/or remotely sensed data. Reviews of complex, contentious, or historical issues are also welcome. We anticipate contributions that focus on themes of: subglacial erosional and depositional processes, landform genesis, stratigraphy, geochronology, geochemistry, paleoglaciological reconstructions.

SS07 - Anything but Boring: the Grenville Orogeny a Key into Mesoproterozoic Geodynamics, Chairs: Aphrodite Indares (, Caroline lotout (

Global tectonic regimes in the Mesoproterozoic are the topic of heated debate, with end members invoking fragmented and active to single-lid and quiet lithosphere(s). The existence of orogens is clearly demonstrated during this time interval despite their tectonic style appearing to differ drastically from modern ones. This session explores distinctive characteristics of Mesoproterozoic orogens by focusing on the Grenville province and its wider context. We hope to bring together new insights on synorogenic magmatism, metamorphic P-T gradients and timescales of metamorphism, that can inform on thickness of orogenic crust, thermal regimes, and tectonothermal evolution. In a broader sense, we encourage contributions to any aspect of Mesoproterozoic plate tectonics. We welcome all types of studies from field-based, magmatic, metamorphic, geochronological, to numerical modeling and geophysical perspectives, and multidisciplinary approaches that integrate across research areas.

SS08 - Archean Craton Assembly, Chairs: Antoine Godet (, Carl Guilmette (, Doug Tinkham (

A fundamental outstanding question in Earth sciences is what kind of tectonics operated during the Archean, and when and how did plate tectonics initiate and evolve. The global convection regime is argued to have evolved from early tectonic regimes, including plume tectonics, asymmetric subduction, multiple juvenile arc-accretion, and mantle overturn tectonics, into modern global plate tectonics. The occurrence of contrasting plutonic and tectonometamorphic styles during the Neoarchean and Paleoproterozoic Era implies that this period was a pivotal point, but the timing, duration, and geological expression of this transition are still debated. We invite multidisciplinary research that aims to better understand Archean craton assembly worldwide.

SS09 - Canadian Journal of Earth Sciences at 60: Celebrating Canadian Geoscience and Geoscientists, Chairs: Sally Pehrsson (, Brendan Murphy (

It is designed as a companion to the 2-day workshop W02 - Environmental Remediation: Global Lessons from the Sudbury Story.

SS13 - Geobiology of the Late Archean to Early Paleoproterozoic Surface World and its Impacts on Proterozoic Evolution, Chairs: Michael Babechuk (, Leslie Robbins (, Galen Halverson (, Kurt Konhauser (

The late Archean to early Paleoproterozoic was a critical time in the co-evolution of life and Earth’s surface environment. It included the formation of large and emergent continents, the relatively rapid oxygenation of the atmosphere, unprecedented acid rock drainage, several global glaciations, periods of high marine primary productivity, the evolution of aerobic metabolisms, and potentially the origins of eukaryotic cells. This session encourages contributions documenting novel approaches and insights that may include chemostratigraphy and detailed sedimentology, non-traditional stable isotope geochemistry, modelling approaches, geomicrobiology, phylogenomics, or the statistical analysis of large datasets, amongst others. We seek a diverse array of presenters and particularly encourage submissions from early-career researchers and graduate/undergraduate students.

SS14 - Geophysics for Minerals and Mineral Systems, Chairs: Richard Smith (, Callum Walter (, Hema Sharma (, Rajesh Vayavur (

This session will discuss the latest innovations in geophysics in the exploration for and understanding of mineral deposits and the associated mineral systems. The methods can use active and passive sources and be deployed on airborne vehicles, on the ground, or down boreholes. The studies can be regional, extending to mantle depth, or local to the ore deposit.

Extreme iron enrichment is common in a range of distinct but mineralogically similar critical mineral-rich deposits. As the demand for critical minerals grows, so will our need to understand the metasomatic and magmatic processes leading to Fe and critical metal enrichment in IOCG, IOA, metasomatic iron, nelsonite, carbonatite, and magnetite-rich cumulate, and other iron-rich deposits types within the broader context of their host mineral systems. In this symposium, we invite talks on the field geology, metallogeny, petrology, mineralogy, geochemistry, and fluid/melt evolution of Fe-rich critical mineral systems with the aim of illuminating intersections in genetic mechanisms and feedback between magmatic, metasomatic, and tectonic processes in forming Fe-rich critical mineral-rich deposits.

SS19 - Isotopes in Ore Deposits and their Utilization in Exploration, Chairs: Bertrand Rottier (, Crystal Laflamme (, Guillaume Barré (, Georges Beaudoin (

Ore deposits are loci where mass and energy concentrative processes take place, and isotopes are unrivalled indicators of the variety of processes involving these material fluxes. Although not yet regularly employed in mineral exploration programs, isotopes have the potential to be powerful tools to understand metal and volatile sources, depositional ages, and as fertility indicators and vectoring tools. We invite studies pertaining to the advancements in analytical techniques and our understanding of how isotope systems including light and metal stable isotopes, radiogenic isotopes and clumped isotopes can be used in mineral exploration.

SS20 - Lithium in Pegmatites: Mineralogy, Petrogenesis and Classic to Innovative Exploration Techniques, Chairs: Tania Martins (, Axel Muller (, Joana Cardoso-Fernandes (, Encarnacion Roda-Robles (, Lee Groat (

Pegmatites are an important source of many of the elements considered critical, particularly lithium, cesium, tantalum, tin, and beryllium. Lithium is a particularly critical element, as it is a key component in batteries for electric vehicles and is vital to Canada's and the European Union's growing green economy and the decarbonisation transition. We invite presentations that will further our knowledge of these enigmatic rocks, e.g. pegmatite mineralogy, petrogenesis, and classic to innovative exploration techniques.

SS21 - Mineral Exploration Footprints, Chairs: Stéphane Perrouty (, Kevin Ansdell (, Robert Lee (

W05 - Orogenic Gold Deposits, Leaders: Jochen Kolb (, Georges Beaudoin (, Iain Pitcairn (, Nicolas Thébaud (, Sponsor: SGA, Duration: 1 day, pre-meeting, May 23-24, WGMC room B8030

This workshop will feature up-to-date geology, structure, and geochemistry of orogenic gold deposits. It will delve into the origin of hydrothermal fluids from source rock P-T-X-t conditions to gold deposition mechanisms in localized mineralized zones. It will review leading genetic models in relation to important provinces hosting orogenic gold deposits and address atypical and controversial examples.

W06 - Reflectance Spectroscopy for Mineral Exploration, Leaders: Philip Lypaczewski (, Derek Wilton (, Gary Thompson (, Sponsor: CNA, Duration: 1 day, post-meeting, May 28, WGMC room B5017

Reflectance spectroscopy (or hyperspectral imaging) is increasingly being used by exploration companies to understand mineralogical alteration patterns surrounding potential deposits. Fast data acquisition rates and the capability to objectively identify even fine-grained hydrothermal alteration make of these instruments powerful tools for vectoring towards mineralization. This workshop will provide a theoretical introduction to reflectance spectroscopy, case-studies in mineral exploration, and an introduction to the practical use of point instruments (e.g., ASD Terraspec, Halo, or Spectral Evolutions oreXpress) that will be available for the analysis of samples.
