Biography
Dr. Rebecca O. Swinscoe (Salvage) is a Research Scientist at the Geological Survey of Canada/Natural Resources Canada within the Critical Minerals Geoscience and Data program. Her research focuses on using geophysics (seismic, fiber optic technology) to identify structural controls for critical minerals in Canada, as well as using remote sensing satellite techniques to identify mineral systems. From 2018 to 2023, she was a Research Associate at the University of Calgary, with research focused in fault and fracture activation and propagation over different time and spatial scales, in particular in relation to resource development projects. From 2016-2018 she was a Profesor Visitante at the Observatorio Vulcanologico y Sismologico de Costa Rica, undertaking real-time monitoring, processing and analysis of tectonic and volcano seismicity in Costa Rica and Central America. She obtained her Ph.D. in Geophysics (Volcano Seismology) from the University of Leeds, UK in December 2015 and holds a Master’s degree in Geology from the University of Bristol, UK (2011).
Research
Areas of Research
Mineral deposits are commonly found along local and regional discontinuities which form geological and structural traps for migrating fluids in the subsurface. Using innovative geophysical techniques (e.g. fiber optic sensing), as well as more traditional techniques (e.g. geophones), I am interested in characterizing and imaging potential mineral fluid pathways (faults, fractures, zones of alteration) in the subsurface, in areas with high potential for critical mineral content.
Natural and induced seismicity are widespread across Canada, although most seismic events are too small in magnitude to be felt at the surface. Current research interests include understanding and characterizing aftershock patterns, assessing potential seismicity associated with new energy initiatives (e.g. CCUS, geothermal), as well as distinguishing between natural and induced seismic events in Canada in a timely manner.
