Raymond Caron is a Ph.D. Candidate in Earth Sciences who is co-supervised by Dr. Michel Chouteau and Dr. Claire Samson. His research is also supported by industry specialist Dr. Martin Bates from Sander Geophysics

Raymond was recently awarded a travel bursary by the Society of Exploration Geophysicists (SEG) to attend its annual meeting in New Orleans from October 18th - 23rd, 2015. He made an oral presentation on his latest research results at this conference. 

Raymond completed the first study in the world using an airborne platform with transient electromagnetics to detect the thickness of an overburden, overlying, glacially eroded bedrock to create a map of the bedrock topography. He used the data he collected to correct for the gravitational effect of the overburden on airborne gravity data, in order to increase the sensitivity of airborne gravity at resolving structural features in the bedrock that could facilitate the exploration of minerals. Raymond’s conference abstract is available here. His research was sponsored by Carleton University, the National Science and Engineering Council of Canada (NSERC), and by Sander Geophysics, which is an international airborne geophysical survey company based in Ottawa.  

Large areas of bedrock in Canada, such as the Abitibi mining region and the interior plateau of British Columbia, are covered by a thick, glacially derived overburden. This overburden complicates mineral exploration by covering the bedrock from exploration geologists, thereby hiding geological information. Another undesirable effect of overburden is the creation of anomalies in gravity data that can be mistaken for a mineral deposit. These anomalies can be of a similar size and amplitude as a signal from a deeper target, such as an ore body, and can conceal, misrepresent, and even mimic the gravity signal of that ore body. Misinterpretation of these anomalies can increase the cost of exploration drilling campaigns. The results of this study are focused on mineral exploration, however, the technology is also applicable to urban planning and resource management. 

Raymond enjoyed his experience at the conference. The contacts and the exposure were so good that he plans to return.
