A GEOTEK multi-sensor core logger (MSCL), originally developed to log soft-sediment cores, has been adapted to allow simultaneous measurement of a range of petrophysical parameters on diamond drill core. The system can measure the density, P-wave velocity, electrical conductivity, and magnetic susceptibility of either whole or half core. It also acquires high-resolution digital colour imagery of the core. System operation, sensor modification, sensor calibration, data accuracy, and repeatability are described in this paper. With careful calibration and close adherence to logging protocols, accuracy and precision of a few percent can be achieved with the MSCL in routine operation. The system is currently being used to record detailed petrophysical data on archival drill core from metalliferous mines for correlation with metallurgical parameters, but it has significant potential in mineral exploration and environmental applications as well. © ASEG 2008.
