Abstract

La présente invention a trait à un procédé et un appareil (20) pour la réalisation d'exploration électromagnétique de la surface terrestre. Au moins un enroulement primaire (12) est prévu. L'enroulement/les enroulements primaire(s) est/sont alimenté(s) pour la génération d'un champ électromagnétique primaire et la surface terrestre est exposée à ce champ primaire. Un récepteur est prévu pour la détection d'un champ secondaire généré par la terre suite aux courants qui y sont générés par le champ primaire. Des enroulements d'annulation espacées (14) sont alimentés de manière à annuler le courant primaire dans un volume tridimensionnel entourant le récepteur, permettant ainsi la détection vectorielle du courant secondaire par le récepteur.
