GU Report 8 - A magnetotelluric survey along part of the 2006 central Victorian seismic transect
| ||||||||||||||||||||||||||||||
Product description:Introduction The basic principle of the MT method relies upon the propagation of plane-wave EM fields from the relatively non-conductive air into the comparatively highly conductive Earth. The amplitude and phase relationships of the electric and magnetic fields at the surface are dependant on the electrical properties of the subsurface within which the EM fields propagate. Thus allowing the conductivity of the underlying surface to be investigated. The technique therefore has little environmental impact, another hugely appealing aspect of the MT approach. The drive for this MT survey was to acquire MT data along a seismic survey line and then compare the EM and seismic data in order to ascertain how well the two sets correlate. The “Central Victoria Seismic Transect” was performed by the Department of Primary Industries, GeoScience Victoria (State Government) in 2006. Its primary purpose was to determine the subsurface structure, which may hold a relationship to the distribution of gold deposits in the central region of Victoria. This current report deals with a brief review on the theory of remote reference MT, data acquisition procedure, data processing and analysis, and finally 2-D interpretations of MT data acquired in the survey.
