Figure F13. Line GeoB 01-035 and Site 1262 plotted along with age estimates of prominent reflectors. R1 is a regional reflector that marks a local unconformity. Although time transgressive, sediments below the reflector tend to be Paleogene and sediments above the reflector are Neogene. The estimated depth of the P/E boundary reflector (RP/E) is 126 mbsf, and the estimated depth of the K/P boundary (RK/P) is 198 mbsf (mean velocity = 1.8 m/ms). Both reflectors can be traced over most of the ridge. CDP = common depth point. V.E. = vertical exaggeration.
