Workshops and Short Courses

Geochemical data collection, preparation, analysis, and presentation
½ Day (4 hours of Formal CPD)

Cliff Stanley, Ph.D., P.Geo., Professor of Applied Geochemistry, Department of Earth and Environmental Science, Acadia University
Friday, February 2, 2024, 1:00-5:00 p.m., Carleton Room, Crowne Plaza Hotel, Moncton NB,

This ½ day (afternoon) short course presents to the geoscientist the basic principles that need to be considered when collecting, preparing, and analyzing geological samples for quantitative data interpretation. It describes several practical steps necessary to make such data useful, including QAQC, data censoring, and data transformation. Finally, it reviews some basic considerations related to initial data evaluation, univariate interpretation, and data presentation. While focused primarily on geochemical and mineralogical data, many of the principles presented also apply to the treatment of many forms of geophysical data.

  • Sample collection
    • Spatial representativity
    • Punctual representativity
  • Sample preparation
    • Mass reduction
    • Particle size reduction
    • Geochemical analysis
      • Assays and geochemistry
      • Mass and molar concentrations

Special Sessions

Session S1: From Ocean Crust to Mountain Peaks: A Celebration of the Career of Sandra Barr
Co-chairs: Deanne van Rooyen and Chris White
This session is a celebration of the long and varied career of Dr. Sandra Barr. From her early work in seafloor rocks to her life-long interest in the Appalachians Sandra has been at the forefront of the advances in geological research for decades. Her work is recognized worldwide, and she has been a mentor and guide to countless students and professionals. We invite contributions dealing with any of the fields of research to which Sandra has made contributions to celebrate the career of one of the preeminent geologists in Canada.

Session S2: Gold in the Northern Appalachians Co-chairs: Aaron Bustard and Mitchell Kerr
Geological Surveys Branch, New Brunswick Department of Natural Resources and Energy Development, Saint Mary’s University

Given heightened interest in gold mineralization throughout the region in recent years, this session will focus on work that is advancing our understanding of gold mineralization in Atlantic Canada. 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.

Session S3: Sedimentary Successions through Time
Co-chairs: Lynn Dafoe, Jade Atkins, Olivia King, and Luke Allen
Geological Survey of Canada (Atlantic), Joggins Fossil Institute, Saint Mary’s University, University of New Brunswick

The nature of the stratigraphic record varies through geological time because of factors such as biological and landscape evolution, as well as broader plate tectonic activity. The application of sedimentological and paleontological principles, however, remains key in understanding ancient and modern depositional settings. In some instances, “the present is key to the past”, but this is not necessarily the case as the rock record is punctuated by catastrophic events and represents an incomplete record. The goal of the session is to show linkages and dissimilarities between sedimentary studies through geologic time. Accordingly, we invite contributions that focus on paleontology, sedimentology, and stratigraphic sections from the Precambrian through Holocene.

Session S4: Igneous-hydrothermal systems and critical metals in the northeast
Co-chairs: Michael Powell and Pēteris Rozenbaks, Department of Earth and Environmental Sciences, Dalhousie University
The global race to build greener economies, coupled with recent federal and provincial government initiatives, have spurred a growing demand for critical metals. Enhancing our understanding of the formation of critical metal resources during igneous and hydrothermal ore system evolution is key to maximizing our discovery and extraction of such resources. This session aims to gather the latest studies of critical metals related to magmatic and hydrothermal systems within eastern Canada and the northeast USA. Contributions are welcome from all domains of igneous petrology, hydrothermal environments, and economic geology.

Session S5: Educational outreach, EdGEO, and outreach opportunities Co-chairs: Tracy Webb and Jason Loxton
Chair of Education Committee; Cape Breton University Geology

This will be an open session to discuss the EdGEO program and look for ways to further extend the resources and workshops for outreach. EdGEO has a proven success record in this nationally, and we would like to support this more in the Maritimes, along with other sources of educational outreach. Please join us and feel free to share your outreach stories, ideas and successes!

Session S6: Environmental geoscience and sustainability Co-chairs: Cameron Greaves and Carla Skinner
Department of Earth and Environmental Sciences, Dalhousie University and Geological Survey of Canada (Atlantic)

“We do not inherit the earth from our ancestors, we borrow it from our children” (Unknown). Ongoing announcements by all levels of government on greenhouse gas reduction, renewable energy, critical minerals, waste disposal, and environmental assessments mean there is a critical need for geoscience data and research. This session calls for research from all geosciences to share their work on these topics, and may include other areas such as geohazards, shallow seismic, coastal/nearshore mapping, sediment mobility, carbon capture, offshore wind, etc. We invite a broad range of topics associated with environmental geoscience and sustainability because the future requires a broad range of solutions.

Session S7: The Energy Transition and Achieving Carbon Neutrality
Chair: Grant Wach, Basin and reservoir lab, Dalhousie University
Throughout human history, as societies evolve and improve, our actions have been contributing to a shift in the natural order of the Earth. From the advent of agriculture, the age of industrialization, advancements in technology, and exponential population growth, there is no doubt about the impact we have made on the globe. While much of this progress is seen as essential for the development of humanity, some of the negative influences – pollution, deforestation, greenhouse gas (GHG) emissions – have been compounding into significant issues. Our emissions have been of rising concern as of late, as GHGs such as methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) absorb and trap heat within the atmosphere, leading to rising global temperatures. As temperature is intrinsically connected to numerous earth processes and cycles, the effects had on sea level, agriculture, and general quality of life could be catastrophic if not dealt with.
With hopeful emission reduction targets in place both federally and provincially for 2030 and beyond, it is apparent that action is needed to change our approach to energy usage, manufacturing, and our relation to the land we reside within. While emission amounts vary between nations due to differences in levels of industrial and technological development, we can only be responsible for dealing with our own emissions; and as one of the most advanced countries in terms of economy and technology, with the means to address the issues head on, Canada should be setting the precedent for making progress in the fight against climate change.
