Resistivity-at-the-bit image showing all interpreted fractures. Fractures are
separated into conductive (blue) and resistive (red) fractures. Tadpoles show
fractures as dip direction with respect to north and dip (0°-90°). Deformation
intensifies significantly at the frontal thrust zone (389-414 mbsf), a fractured
interval also seen in Leg 131 Site 808 cores (559-574 mbsf), and the
décollement zone (~950 mbsf). An interval of continuous strong borehole
breakouts at ~270-530 mbsf coincides with log Unit 2 and brackets the frontal
thrust zone. Fracture orientations are dominantly northeast-southwest (dip
directions northwest-southeast) within the frontal thrust zone and 560-mbsf
fractured interval, but are more variably oriented with depth. A north-south
fracture orientation (east-west dip direction) is dominant within the
décollement zone.
