Domaine(s)
  • Prospection magnétique et électromagnétique
CONT

Les recherches électromagnétiques et de résistivité servent à localiser les gisements de sulfures métalliques bons conducteurs, ou les gisements non métallifères, qui sont généralement mauvais conducteurs.

CONT

Les prospections électromagnétiques aériennes et terrestres se sont surtout révélées utiles dans des régions où existent des gisements de sulfures non altérés ou souterrains, comme dans le Bouclier canadien.
