Offshore ert survey
Webb10.3.3.5 Electromagnetic. Electromagnetic (EM) survey, both airborne and ground, is one of the most commonly used methods in mineral exploration. The technique is proficient in direct detection of conductive sulfide deposits, in which large conductivity contrasts exist between the orebodies and country/host rocks or thin overburden cover.
