• Why use it?

    Magnetic susceptibility is used to ascertain how easily a formation can be magnetised.

    Alteration and oxidation zones from formations hosting Iron and pyrrhotite are the most common targets for delineation with the probe.

    This is a two coil sonde designed to measure apparent formation magnetic susceptibility.

    Field applications include

    • Grade control (iron ore) & delineation of the hardcap in magnetite deposits.
    • Uranium exploration
    • Defining mineralised zones and the various degrees of alteration in deposits.
    • Long term water well monitoring (salinity)
