2009 Canadian Society of Exploration Geophysicists (CSEG) Distinguished Lecturer 2009/2010

Research Interests

Richard Smith joined Laurentian after spending 20 years working in the exploration business. He has extensive experience, working as a research scientist, an exploration geophysicist and a manager. He has international experience in the application of geophysics to lead-zinc exploration, hydrocarbon exploration and environmental issues. Richard is most familiar with the following geophysical methods: electromagnetics, magnetics, induced polarization and gravity. These types of data can be acquired on the ground, from aircraft, and below the earth surface in boreholes or in mines. Professor Smith has been involved in the development of the GEOTEM, MEGATEM, HeliGEOTEM systems and processing of TEMPEST data. 

My main research interests are in the application of geophysical methods to the discovery of mineral deposits and hydrocarbon and water resources. In particular, I am interested in using geophysical methods to create an image of the earth that reflects the physical properties of the material below the surface of the earth. These images can in some cases be used to infer the geology.

My current research is focused towards developing new geophysical tools for solving geological problems.  Projects focus on airborne and ground geophysics, cross-hole radio imaging and physical properties measurements.
