Research Focus:
- Exploring and imaging the structure of the crust and upper mantle
- Unravelling the tectonic history of the North American continent
- Understanding the tectonic processes that control the evolution of the lithosphere
- Developing new techniques to image:
- lithospheric structure and
- upper crustal kimberlite dykes (with applications in diamond exploration and mining)
- Investigating the exploration potential for offshore BC oil & gas and evaluating related environmental risks
Active Source Group
Current Research:
- Lithospheric structure and tectonic history based primarily on seismic refraction,
seismic reflection, potential field data, and structural geologic analysis:
- northern Canadian Cordillera (BC, YK)
- Slave Province (NWT)
- Trans-Hudson Orogen (SK, MN)
- Juan de Fuca and Explorer Plates (BC)
- Near-surface seismic reflection exploration related to diamond and ore emplacement with application to mining issues (industry collaborators: DeBeers and Diamondex)
- Finite-difference investigations of Moho reflectivity
- Development of reflection and refraction processing and analysis software (e.g., Plotsec)
Teleseismic Group
Current Research:
- POLARIS: A broad-band and MT array designed to investigate lithospheric structure, continental dynamics, and earthquake hazards in Canada
- Teleseismic wave propagation in laterally heterogeneous, anistropic media
- Numerical applications of inverse scattering theory to teleseismic wavefields
- Lithospheric stabilization and modification in the southeastern Canadian Shield
- Nature of the Continental Moho
- Imaging the Cascadia subduction zone
- Teleseismic receiver function analysis in the Trans-Hudson Orogen (SK)
- Coda Q in southwestern British Columbia
