Dynamic and static Formation MicroScanner (FMS) image and NGR logs across the
lithologic Unit III/IV boundary that was placed at a 1-cm-thick layer of
grainstone with a sharp contact at 177 mbsf. This boundary coincides with a thin
highly resistive layer capping a lower resistive bed on the FMS log. The layer
also marks the change in bedding character from thin-bedded and highly resistive
strata below to thick-bedded and more conductive strata above.
