MAGNETIC SUSCEPTIBILITY

QL40 MGS


The QL40 MGS combines the Bartington BSS-02B sensor and the ALT electronic interface. The probe is designed for measurement of magnetic susceptibility and is optimized for small diameter boreholes.

The magnetic susceptibility probe is generally used in mineral exploration and for stratigraphic correlation. It is ideal for characterising iron ores and for measuring the extension of ore bodies. Other applications include the delineation of  diamond-bearing rocks, paleosoil susceptibility studies and identification of alteration fronts associated with some ore deposits.

The QL40 MGS is supplied as a bottom sub. It can be combined with other logging tools of the QL (Quick Link) product line or can be operated as a standalone tool. It is compatible with Matrix, Scout and ALTlogger acquisition systems.
