Figure F301. Comparison of vertical magnetic field component measured by the Goettingen Borehole Magnetometer (GBM) with photoelectric factor (PEFL) logging data and magnetic susceptibility measurements on cores (Hole U1309D). GBM data were averaged over 15 data points. The data reveal a correlation for high magnetic susceptibility in serpentinized cores (green) and oxide gabbros (gray) shading showing high PEFL values and high variations within the vertical magnetic flux density (z-component).
