Sub-Audio Magnetics – Gap Geo

    https://www.gapgeo.com/sub-audio-magnetics/
    Sub-Audio Magnetics (SAM) is a proprietary survey technique which requires a geophysical transmitter to transmit a precisely controlled signal into either an inductive transmit loop or a grounded dipole in order to induce secondary fields in sub-surface conductors. Using Gap GeoPak transmitters, currents of up to 200A are normally achieved with ...

    2018-12-7 · A Sub-Audio Magnetic (SAM) survey over an exposed section of the Lena Shear recorded anomalous equivalent magnetometric resistivity (EQMMR) values proximal to the shear, but not directly associated with the geologically mapped location of the shear as expected. An interpretation of the Sub-Audio Magnetic survey highlights current channelling in ...
