Notes: MST = multisensor track, NGR = natural gamma radiation, NGT = natural gamma tool logging data, cps = counts per second, Nd = not determined. MST-NGR data >3 cps is significant; for data >3 cps, the calibration is used; and for data <3 cps, an average value for minimum altered basalt is used (0.08 wt% K2O).
