Secular evolution and metallogeny of continental margin basins
Lithospheric architecture has a fundamental control on the secular evolution and metallogeny of rifted continental margins. Our group is targeting the stratigraphic record adjacent to key lithospheric structures in western Canada to investigate the driving forces behind non-arc volcanism, basin paleogeography and redox conditions, and sediment-hosted sulphide mineralization. This research is supported by Natural Resources Canada (Geo-mapping for Energy & Minerals Program), Yukon Geological Survey, and NSERC.
Source-to-sink studies of sedimentary basins
In the source-to-sink approach, a geologist interprets the process-response relationship between upstream areas with long-term erosion and sediment transport and downstream areas with long-term deposition and sediment burial. Our group is studying the Jurassic-Cretaceous rift-related stratigraphy of offshore Newfoundland to identify the timing and spatial extent of rift shoulder uplift, sediment source regions, and the burial-thermal histories of known and prospective reservoir intervals. This research is supported by the Research and Development Corporation of Newfoundland and Labrador.
Tectonics and paleogeography of ancient orogens
Sedimentary rocks provide an opportunity to understand the precise age, spatial extent, and exhumation histories of old mountain belts. Current projects in the Canadian Cordillera, Newfoundland Appalachians, Svalbard Caledonides, and other localities are using the stratigraphic record to decipher the tectonic evolution and paleogeography of North America and its ancient continental margins. This research is supported by Yukon Geological Survey and NSERC.
Reservoir quality and sandstone provenance
Sandstone diagenesis and porosity evolution are impacted greatly by the composition, texture, and source of clastic sediment. Once known, this information allows a better understanding of vertical or lateral stratigraphic changes in reservoir quality that may reduce the risk for petroleum explorationists. Our current field and SEM-MLA laboratory research on reservoir quality and porosity evolution is supported by the NL Department of Natural Resources and Nalcor.
