Figure F2. Locations of Site 1267 and DSDP Site 527 along Line GeoB 01-039. R1 is a regional reflector that marks an unconformity or condensed interval. Although time transgressive, sediments below the reflector tend to be Paleogene in age and those above the reflector tend to be Neogene. The Paleocene/Eocene boundary reflector (RP/E) is estimated to be at 216 mbsf, and the Cretaceous/Paleogene boundary (RK/P) is estimated to be at 279 mbsf. Both reflectors can be traced over most of the ridge. CDP = common depth point.
