Donnelly Archibald

Donnelly Archibald is a Senior Lab Instructor and Adjunct Professor in the Department of Earth and Environmental Sciences at St. Francis Xavier University. He holds a PhD from the University of Adelaide (2016), specializing in Neoproterozoic tectonic evolution of Central Madagascar. His research focuses on mid-Palaeozoic tectonic development in Atlantic Canada, particularly the Northern Appalachian Orogen. He employs zircon geochronology, whole-rock geochemistry, and isotopic analyses to study ancient tectonic environments.

Education: PhD in Geology, University of Adelaide (2016).

Research interests include tectonic evolution, magmatic processes, and isotope geochemistry with a focus on Proterozoic to Paleozoic geological systems. Key areas include the Meguma and Avalon terranes in Nova Scotia, and crustal growth dynamics in the Caledonides and Appalachian Orogen.

His recent work examines Devonian plutonism in the Meguma terrane, Ordovician magmatism in the Antigonish Highlands, and the tectonic implications of LCT pegmatites. He has contributed to studies on mantle-derived water in appinite complexes and the genetic relationships between mafic and granitoid plutons.
