Characterization of Geotomographic Studies with the EMRE System
Figure 6
(a) A possible multipath effect (Rayleigh scattering) at 442–457 m. The phase has suddenly changed by ~130 degrees, meaning a longer path of ~ for the multipath wave. The change in the phase at ~427 m is due to the presentation mode (−180°to +180°). Due to the presentation mode, the phase is plotted between −180° and +180°. (b) Recording in a massive sulphide deposit.
