Figure F6. Comparison of natural U concentration logs. Stacked Multi-Sensor Spectral Gamma Ray Tool (MGT) and Schlumberger gamma ray tool (HNGS) data are shown from 160 to 230 mbsf in Hole 1179D. The peak-to-peak correlation is good only for HNGS values of ~2 ppm or more. MGT values are ~1-2 ppm higher than the HNGS.
