ODP Leg 186: Western Pacific Geophysical Network Logging Summary

Figure 4

FMS images across a carbonate zone at 943.3-944.4 mbsf in Hole 1150B, which were recovered in Core 186-1150B-26R and were correlated to major seismic reflector. The images show the carbonate zone consists of two parts: relatively resistive beds with conductive features (bioturbation?) below and relatively conductive beds with fractures above. The images to the left are displayed with a range of resistivity values that are fixed for the entire logged interval (static correction); the images at the right allow for a greater range of grayscale to be displayed using normalized gains for a smaller user-specified depth interval (dynamic equalization). Both images are from 940 to 948 mbsf.
