Plenary Address

Friday February 11th @ 7pm:
Application of Ore Deposit Models for Critical Mineral Assessments: Examples from Maine, USA – John Slack (USGS)

Special Sessions

Advances in clastic sedimentary systems: from rivers to the deep ocean
David Lowe1, Lillian Navarro2
1: Earth Sciences Department, Memorial University of Newfoundland
2: Department of Math, Physics, and Geology, Cape Breton University

Clastic sedimentary systems contain an intricate record of sediment fluxes from weathered bedrock (hinterland) to basins. The sedimentary record provides valuable insights of sediment supply, the nature of source material, and environmental conditions that can ultimately control sediment source composition and resulting depositional architecture. We invite contributions from field-based and analytical studies that advance our understanding of modern and ancient clastic sedimentary systems in terrestrial, shallow marine, and deep marine realms; particularly those that focused on sedimentation processes, geomorphological evolution, provenance, source-to-sink dynamics, and the response of sediment-routing systems to tectonics and climate change.

Regional Geology in the Northern Appalachians or Development of the Northern Appalachians: New Data and New Thoughts
Chunzeng Wang1, Alan Fernando Cardenas Vera2
1: University of Maine at Presque Isle
2: Department of Earth Sciences, University of New Brunswick

The Northern Appalachians were developed through an elaborate process of accretion and collision of peri-Laurentian and peri-Gondwanan terranes to the Laurentian margin during the closure of the Iapetus and Rheic oceans between the late Cambrian and the Permian. This special session invites contributions that focus on the regional geology and tectonic evolution of the Northern Appalachians with new data and new thoughts. Works from field, experimental, modelling, and interdisciplinary perspectives are welcome with an aim at further understanding of the development of the Northern Appalachian Mountains.

Current research in the Carboniferous basins of the Maritimes
Adrian Park, Steve Hinds
Geological Surveys, New Brunswick Department of Natural Resources and Energy Development

Contributions are welcomed dealing with tectonics, structural studies, geochronology, paleontology, palynology, sedimentology, etc, pertaining to the evolution of the Carboniferous (late Devonian to Permian) basins in eastern Canada and adjacent areas.

Minerals Resources and Metallogeny of the northern Appalachians
Aaron L. Bustard 1,2, Fazilat Yousefi 2
1: Geological Surveys Branch, New Brunswick Department of Natural Resources and Energy Development
2: Department of Earth Sciences, University of New Brunswick

Our understanding of the diverse mineral deposits in the northern Appalachians and their relationship with geological evolution is continuously developing. We invite papers from industry, government, and academia related to research on all deposit types found in the region, including precious, base, and critical metals, and associated metallogenic processes. Topics may cover all aspects of mineral deposits research including controls on deposit formation, structure, metal transport, isotopes, alteration, exploration models, and relationships to geodynamic processes. This session will facilitate discussions on recent developments in the fascinating field of Appalachian mineral deposits, metallogenesis, and associations with geological evolution.

Trace Elements in Crystalline Rocks: Abundances, variation, and geochemical interpretation 
Bryan Maciag1, Dalhousie University; James Brenan1, Dalhousie University; Erin Adlakha2
1: Department of Earth Sciences, Dalhousie University
2: Department of Geology, Saint Mary’s University

The geochemical variation of trace elements in crystalline rocks and their constituent minerals offer a window into a myriad of processes that occur in the rock cycle. These processes include crystallization of magmas, syn to post-magmatic/hydrothermal alteration, ore formation, weathering and, metamorphism.  This session invites contributions from researchers studying all aspects of the trace element geochemistry of crystalline rocks, including methods of measurement, observations on element variations, laboratory calibration of trace element behaviour, and geochemical modelling.  Our goal is to develop linkages amongst diverse researchers to improve our understanding of trace element behaviour, and the importance of trace elements to society.  

Advances in Palaeontology
Olivia King, Matt Stimson
Saint Mary’s University and New Brunswick Museum

Paleontology is a broad topic in geology that bridges biology of ancient organisms with sedimentology and other aspects of geology. It’s a tool to determine stratigraphic position and relative ages of rocks, helps reconstruct ancient organisms, their paleoecology and infer paleoecosystems. This session invites contributions from researchers studying all aspects of the field of pure paleontology or its application to our understanding of paleoecology, paleoclimatology, paleoenvironments and biostratigraphy. Our goal is to develop a broader understanding of the evolution of environments and the organisms that lived within them throughout geological time.

Resources, Remediation, and Environmental Protection: Surficial Geochemistry and Geology Studies
Mohammad Parsa; Allison Enright
Department of Earth Sciences, University of New Brunswick, Fredericton, New Brunswick, Canada

This session will explore surficial geochemical and geological studies, including analyses of sediments, rocks, and fluids, as well as novel analytical approaches to these environments. We invite abstracts with themes of environmental protection, resource exploration and management, and remediation, from any region. Contributions from industry, government, and academia that address (i) surficial geochemistry, (ii) surficial geological processes, including landforms and sediments, and (iii) state-of-the-art methods of processing, analyzing, and interpretation of geochemical data are welcomed for this session.

The 8Gs: A New Paradigm in our Geologic Heritage
Ann C Timmermans1 and Tracy Webb2
1University of New Brunswick; Quartermain Earth Science Centre; 2Atlantic Geoscience Education Committee

Atlantic Canada’s recognition of the global significance of geological heritage and its value to science and society is growing. The valuable work of geoscientists to collaborate with local, national and international initiatives, seek partnerships with others at all levels in coordinating activities related to the 8Gs: Geo-Diversity, Geo-Heritage, Geo-Conservation, Geo-Preservation, Geo-Tourism, Geo-Sites, Geo-Parks and Geo-Education. The purpose of this session is to invite speakers to share their new and existing endeavours, examine the challenges, and discuss the important societal and social implications of the 21st century and beyond.

Advances in quantifying erosion processes, sediment dynamics, and landscape evolution
Sophie L. Norris, Gerald Raab, John C. Gosse. Dalhousie University, Halifax, NS, Canada

Geomorphic processes (e.g fluvial, marine, erosional, tectonic, gravitational, aeolian, glacial) shape landscape and control sediment fluxes in a wide range of environments and spatial and temporal scales. Quantifying these processes requires an understanding of their individual environmental elements (natural and anthropogenic) and dynamics responsible for sediment/soil production, mobilisation, storage, transport and deposition. Understanding the interplay of these processes, as well as how external factors affects them, is critical to comprehending landscape evolution.

This inter-disciplinary session welcomes (i) field and model-based research developments (terrestrial and marine), (ii) advances in process understanding, and (iii) statistical or technical assessments of earth surface processes. We encourage contributions from present-day and palaeo settings, and especially those focusing on interactions and links between different geomorphic and sedimentary processes, geohazards, and climate change.

Theory, practice, and new applications of laser ablation inductively-coupled plasma mass spectrometry”

Presented by Prof. Chris McFarlane and Brandon Boucher

Workshop summary:

Laser ablation inductively-coupled plasma mass spectrometry (LA ICP-MS) is used for a variety of geochemical and isotopic investigations.  Minimal sample preparation, low detection limits, high spatial resolution, and high throughput make it an attractive technique for geochronology, trace-element characterization and tracer isotope studies.  This workshop is structured with two main parts: 1) a morning session that covers basic operation concepts, instrumentation, and background theory of laser-target interactions and plasma dynamics; 2) an afternoon session covering applications to geochronology, trace-element characterization, and tracer isotopes including worked examples using Iolite data reduction software.  Along the way we will introduce some new techniques now possible using the Agilent 8900 QQQ-ICP-MS recently installed at UNB Earth Sciences: Rb-Sr, K-Ca, Lu-Hf, La-Ba, and Re-Os isochron dating.
