Content
Richard Smith has recently 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.
My main research interests are in the application of geophysical methods to the discovery of all types of mineral deposits. 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 will be focused towards helping the sponsors of the Industrial Research Chair in Exploration Geophysics develop new tools for solving geological problems.
Students with an interest in using borehole physical properties measurements (density, magnetic susceptibility, resistivity, etc) to infer the geology are welcome to contact me. The project would require collecting physical properties measurements and working with a large database. A sound understanding of statistical methods is a definite advantage. The project is scheduled to start in 2011/2012.
Students with experience or an interest in working with a cross-borehole
electromagnetic method called Radio Imaging (RIM) should contact me. The project
will involve writing computer programs to process and display RIM data. The industrial
partners are very interested in the RIM method and supporting of the project.
There is money available to fund Canadian students for these projects. Foreign
students will need additional sources of funding of about $15000 per year to cover the
cost of foreign student fees and the cost of living in Sudbury.
