Abstract:
My main research focus is on understanding the interaction between cratonic margins and accreted terranes in a wide range of tectonic settings using a combination of field work, structural geology, geochronology, and thermobarometry. The Core Zone of the Southeastern Churchill Province is a complex amalgamation of Archean and Paleoproterozoic crustal fragments now located between the Superior Province and the North Atlantic craton. The collision of the North Atlantic craton with the Core Zone and its subsequent accretion to the Superior margin formed an excellent example of complex interactions between a cratonic margins and transported terranes. The area preserves evidence for multiple types of modern plate tectonic processes including the generation of voluminous flood basalts in the Labrador Trough, lateral extrusion of crustal blocks in the Core Zone, and classic thin-skinned fold-thrust tectonics of the New Quebec Orogen. In this talk I will present highlights from some current research projects in the Core Zone – Superior area and the Cape Breton Appalachians to illustrate how I approach my research with colleagues and students.


BIO: 
Dr. Deanne van Rooyen is an Associate Professor of Geology at Cape Breton University where she is also the co-director and co-founder of the Bachelor of Arts and Science in Environment degree program. She received her BSc and PhD in Earth Sciences from Carleton University. Her main research focus is on understanding the interaction between cratonic margins and accreted terranes using a combination of field work, structural geology, geochronology and thermobarometry. She works extensively in the Appalachian terranes of Cape Breton Island and the Maritimes with projects focussed on structural geology and geochronology. She also works in the New Quebec orogen between the Superior craton and the Archean to Paleoproterozoic Core Zone of Nunavik (Northern Quebec), Nunatsiavut and Labrador.
