Application de la magnetotellurique a l'exploration miniere profonde: Anomalie de trillabelle, structure de Sudbury.

摘要

magnetotelluric survey was completed over a known orebody to determine if the method could be used as reconnaissance tool for deep massive sulphide deposits. The orebody is a deep Ni-Cu-PGE deposit (top at 1900 m) within the footwall breccia of the Sudbury Igneous Complex at the contact with the basement rocks of the Levack gneiss. 11 MT and 8 AMT soundings were recorded over an area approximately 4
