Figure F8. East-west-trending vertical slices through the seismic data around Sites 1251 and 1252. The slice for Site 1252 overlaps and extends through the slice shown in Figure F5. The slice for Site 1251 is offset to the south. Sites 1251 and 1252 are on the east and west flanks of anticline B, respectively. This anticline appears to have been active throughout the depositional history of the slope basin on the east flank of Hydrate Ridge, which included an unconformity (U) and two apparent massive debris flows (DF1 and DF2), which can be traced throughout the slope basin. Reflection AC is an unconformity that marks the top of older (>1.6 Ma) indurated and fractured sediments of the accretionary complex. BSR = bottom-simulating reflector.
