Time-Domain Electromagnetic (TDEM) systems are instruments designed to detect electromagnetic fields andx000D
are used, among other applications, to measure weak signals generated by mineral deposits found deep withinx000D
the Earth's shell. This detection is achieved by emitting very intense time-varying electromagnetic fields thatx000D
interact with these deposits. In turn, the soil's electromagnetic response induces, within a detection device,x000D
signals that are greater than the background or instrumentation noise. Therefore, they can be used by the miningx000D
industry as a fingerprint of the nature and quantity of minerals. That being said, it is obvious that in order tox000D
properly interpret the data, a physically-coherent model must be employed. In the context of this proposal, ax000D
novel integral method will be used to model the electromagnetic response of mineral deposits located at severalx000D
hundred meters beneath the Earth's surface. This model will help Geophysics GPR International Inc. (ax000D
Québec-based company) take into account local variations in the soil's electrical conductivity and consequentlyx000D
refine their current calculation model. Once the methodology will be fully implemented, it is expected that itx000D
will help GPR's operations and consequently contribute towards the development of Canada's mining industry.
