Figure F26. Summary of geophysical logs vs. depth from triple combination logging tool and sonic/geologic high-resolution magnetic tool for the open-hole (lower) part of the cored interval. From left to right, columns are core recovery; gamma radiation (HSGR) and caliper; porosity and density; photoelectric effect (PEF); shallow, medium and deep resistivity; sonic velocity; magnetic susceptibility; logging units; lithostratigraphic units; and biostratigraphic ages.
