Above 850 mbsf, the position of several reversals are evident following AF demagnetization. These should be useful in establishing a few magnetostratigraphic tie points in the Pliocene-Miocene section at this site. The magnetization of the RCB cores from Hole 1150B is fairly stable, and dominantly normal polarity below 850 mbsf. The declinations from the Hole 1150B cores have proved useful for reconstructing structural orientations of the numerous micro-faults and fractures observed in the core. Normal offset is observed on most of the fault planes, suggesting an east-west extensional stress field is responsible for the deformation observed in this interval.
Data quality is good throughout the logged intervals.
The whole logged section can be divided into six units using the resistivity log in conjunction with other logs. These units are consistent with core descriptions and core measurements.
