Figure F3. Line GeoB 01-046 and Sites 1263 and 1264 plotted with age estimates of prominent reflectors. RO/M = the Oligocene/Miocene boundary reflector. R1 = a regional reflector associated with an erosional unconformity. The Paleocene/Eocene boundary reflector (RP/E) beneath Site 1264 is estimated to be at 460 mbsf. RK/P = the Cretaceous/Paleogene boundary reflector.
