Case history of combined airborne time-domain electromagnetics and power-line field survey in Chibougamau, CanadaTime-domain electromagnetics and power lines

Exploration for volcanogenic massive sulfides requires good geologic understanding. Geologic knowledge often is limited by a lack of outcrops. This is especially true in Canada under residual glacial covers. Geologic information must therefore be complemented by information obtained using means such as geophysical and geochemical observations. Electromagnetic (EM) methods extend lithological understanding to depths beyond the overburden. …
