Figure F3. Seismic depth section extending from west of Site 1045 to Sites 676 and 1047 then to Sites 672 and 1044. Solid lines below the level of the décollement zone and proto-décollement zone show approximate limits of the sandy underthrust terrigenous sequence. This sandy sequence may be the zone that migrates warm fluids from beneath the accretionary prism, which generates the observed heat-flow anomaly seaward of the deformation front. See Figure F2 for location of the seismic section.
