Figure F5. Comparison of natural K 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 correlation is excellent with K concentration ranging between 1 and 2.5 wt% and increasing slightly with depth in these sediments.
