Figure F3. Line GeoB 01-046 and Sites 1263 and 1264 plotted with age estimates of prominent reflectors. R1 is a regional reflector associated with an erosional unconformity. Using an average velocity of 1.8 m/ms, the Paleocene/Eocene boundary reflector (RP/E) is estimated to be at ~276 mbsf and the Cretaceous/Paleogene boundary reflector (RK/P) at ~352 mbsf. RO/M = Oligocene/Miocene boundary reflector. CDP = common depth point. V.E. = vertical exaggeration.
