The 2023 AGS Colloquium is being planned for the Inn On Prince Hotel and Conference Centre (formerly the Holiday Inn), Truro, on February 3-5, 2023.

Call for volunteers, sessions and short courses

There is a call for volunteers interested in assisting in the organization of the event, and a call for special sessions and short courses. Deadline: November 9th!

  • It requires participation from several people to run a colloquium. Help is needed to manage registration, solicit sponsorship, organize the program, help out at the colloquium, etc. If you would like to get more involved in running a conference, here is your chance to learn!

Workshops and Short Courses

One short course and two workshops have been proposed – details will be forthcoming soon.

  • Short Course: Rock Engineering Characterization for Geoscientists (Jennifer Day)
  • Workshop: Video Production, the ins and outs (Jason Loxton and the Video Committee)
  • Workshop: pXRF certification (Dave Lentz, Dominique Huot)

Special Sessions

  • The importance of mineral resource development (Luke Hilchie)
    How can a jurisdiction be generally opposed to mineral resource development in its territory, yet seemingly unaware that the operation of our homes, businesses, transportation infrastructure, institutions, etc. impose huge demands for a steady supply of the very raw materials resource development affords? The reflexive ‘mining is bad, conservation is good’ viewpoint only has any legitimacy if the anti-mining perspective insists on reductions in consumer demand for commodities.

  • Marine and coastal geoscience for sustainable development (Cameron Greaves, Jordan Eamer and Ned King)
    With the Government of Nova Scotia’s September 2022 announced target to offer leases for 5 GW of offshore wind by 2030, promising developments in tidal energy generation, and a nascent hydrogen industry that will increasingly depend on renewable energy sources, there is a critical need for geological and geotechnical data to characterize the shallow areas of Atlantic Canada’s continental shelf – areas that have traditionally been under-surveyed due to the challenging conditions, efficacy of surveying shallow waters, and changing government priorities. This session calls for research on Atlantic Canada’s continental shelves and coastlines that have broad applicability to the above issues, and may include:
    • Surficial geology mapping and interpretations
    • Shallow seismic data – correlations, seismostratigraphy, and heterogeneity on our shelf
    • Geohazard investigations (e.g., mass wasting, shallow gas, salt diapirism, fault characterization)
    • Seabed sediment mobility – bedforms and scour
    • Geotechnical characterization of offshore soils and bedrock
    • Coastal and nearshore mapping, erosion, and modeling, in particular the use of the wealth of recently acquired bathymetric lidar (e.g., for cable landfall)
  • Environmental Geoscience (Dave Keighley and Allison Enright):
    • Contaminated lands and waters
    • Environmental Geoscience: carbon sequestration and green energy
      Details TBA

  • New Developments in the Study of Igneous Systems and Associated Critical Mineral Deposits in the Northern Appalachians (Fazilat Yousefi and Donnelly Archibald)
    The northern Appalachians host many igneous rocks that are associated with a variety of critical mineral deposits. Recent advances in the application of petrochronology combined with the geochemical and isotopic signatures of minerals, fluids, melts, and whole-rock samples has yielded valuable information for studying critical mineral systems associated with igneous rocks. In addition, this information can also provide a better understanding of the evolution of magmatic systems. We invite contributions from academic researchers, industry, and government that focus on a broad range of topics associated with critical mineral deposits associated with igneous system in the northern Appalachians.

  • Palaeontological and Sedimentological Advances in Maritimes Geology (Lynn Dafoe and Jade Atkins)
    Sedimentary basins located in the Maritimes region cover a wide range of geological time and history, with varying basin-forming mechanisms and related tectonic processes that affected the resultant stratigraphic succession. The units within these basins contain important fossils that often represent the oldest example of their lineage. These basins have been arguably well-studied in the last century, especially when considering classic sections, such as those preserving Carboniferous stratigraphy, as well as key core intervals collected from offshore and onshore units. Despite the breadth of understanding, new methods and approaches continue to lead to new discoveries and ideas regarding the nature of the stratigraphic record. We invite contributions that address these types of new research results in the fields of palaeontology, sedimentology, and stratigraphy within the Maritimes region.

  • Showcase of developments, programs, and research that promotes education of the earth sciences (Tracy Webb and Education Committee)
    Details TBA

  • Gold in the Northern Appalachians (Aaron Bustard, Kevin Neyedley, and Mitchell Kerr)
    Given the ongoing flurry of gold exploration in Atlantic Canada, this session will focus on current work that is advancing our understanding of gold mineralization in the region. We invite papers from industry, government, and academia related to all aspects of gold deposits including transport and deposition, geochronology, structural controls, geochemistry, and refinement of genetic and exploration models. This session will provide an avenue for discussing the current and future work to further our understanding of gold in Atlantic Canada and beyond.

  • Tectonic interactions of Appalachian-Caledonide terranes and their host continents (Phil McCausland, Shawna White, Deanne van Rooyen)
    This session welcomes contributions related to the tectonic history of the Appalachian-Caledonide orogen with a focus on the interactions between terranes and continents. This can include terrane provenance, terrane-terrane interactions, and terrane arrival at either the Laurentian or Baltican margin. Examples of studies include but are not limited to stratigraphy and sedimentary facies comparisons, paleontology and faunal associations, structural studies of deformed rocks, geochronology and geochemistry of magmatism or metamorphism, and paleomagnetic or geophysical studies.  .

General session

General sessions will be organized depending on availability of papers or posters and grouped in themes. Contributions are welcome on any topic of interest to AGS members.
