Professor in the Department of Geology of St. Francis Xavier University, Antigonish, NS, Canada. He is also an Honorary Research Associate at Acadia University, Wolfville, Nova Scotia and Dalhousie University, Halifax, Nova Scotia.
Field Experience :
Analysis of Neoproterozoic to Carboniferous rocks in Nova Scotia, Britain, NW France. Most field research based in mainland Nova scotia in the Antigonish and Cobequid Highlands and the St. Mary's Basin, analysis of their structural, magmatic, metamorphic and tectonic histories and an assessment of their economic potential.
His research focuses on orogenic (mountain building) processes, with particular reference to Avalonia, the largest suspect terrane in the Appalachian orogenic belt. Avalonia is a well-preserved example of global-scale Neoproterozoic orogenic activity. His research methods include field and laboratory investigations into the Neoproterozoic and Paleozoic evolution of these rocks. Recently, with his colleagues, he proposed models that relate the evolution of Avalonia and coeval global-scale Neoproterozoic orogenies to the amalgamation and dispersal of a supercontinent. Avalonia was originally situated along the periphery of a supercontinent (Vendia) in the Neoproterozoic and Early Paleozoic and became attached to Laurentia some time in the middle Paleo zoic. Therefore, an understanding of its tectonic history has a profound influence on paleocontinental reconstructions for the Neoproterozoic and Paleozoic, and offers an excellent opportunity to study the growth of the North American continent during or ogenesis.
