Northeast Geological Society of America meeting
Sandra Barr joined more than 800 other participants at the annual meeting of the Northeastern Section of the Geological Society of America (NEGSA) in Portland, Maine, March 16th-19th, 2019. The NEGSA is a diverse meeting that provides excellent opportunities for building collaborations with geoscientists and potential graduate students in New England, whose research interests tend to be connected by geographic proximity and geological similarity to Nova Scotia. Sandra gave two oral presentations, the first in a special session on "The Roles of Geochronology and Geochemistry of Granitoid Plutons in Deciphering Orogenic Events", a session which she co-convened with Dr. David Gibson, University of Maine at Farmington. Her talk on "Deciphering tectonomagmatic events in the Ganderian Aspy terrane of Cape Breton Island, Nova Scotia, Canada: juxtaposed early Ediacaran through Devonian arc and within-plate plutons" was co-authored with Acadia MSc students Alicia Moning and Gabriel Sombini dos Santos and Acadia adjunct professors Deanne van Rooyen (Cape Breton University) and Chris White (NS Department of Energy and Mines). Her second oral presentation on "Contrasting Avalonian and Ganderian crust using Lu–Hf-isotopic composition and model ages of Neoproterozoic magmatic zircon grains" was co-authored by Jeff Pollock (Mount Royal University, Calgary), as well as Deanne van Rooyen and Chris White.
Sandra also presented a poster on "New U-Pb zircon ages from the Caledonian Highlands, southern New Brunswick, Canada: implications for magmatic evolution in Avalonia", a collaboration with Susan Johnson and Adrian Park (NB Department of Energy and Resource Development), Greg Dunning (Memorial University), Deanne van Rooyen, and Chris White. In addition, she was a co-author on six other abstracts presented at the conference, a "career high" for presentations at a single conference.
