Figure F85. Summary of natural gamma ray log measurements, Hole U1374A. Note that natural gamma radiation (NGR; measured on whole-round cores) is in counts per second (cps), and all downhole measurements are in gAPI (American Petroleum Institute gamma ray units). Colored zones across the figure denote areas of massive, nonbrecciated units (purple = olivine-plagioclase-augite-phyric, green = olivine phyric, pink = plagioclase-phyric, brown = plagioclase-augite-olivine-phyric, blue = aphyric intrusions). A summary of core recovery and stratigraphic units is provided at far right (see Fig. F18 for explanation of abbreviations and patterns).
