Late cretaceous-cenozoic magnetostratigraphic and biostratigraphic correlations of the South Atlantic Ocean: DSDP Leg 73

January 1, 1983

DSDP Leg 73 sediment cores allow direct calibrations of magnetostratigraphy and biostratigraphy for much of the lates Cretaceous to Cenozoic in the mid-latitude South Atlantic Ocean. A complete record of the Cenozoic was not obtained, however, because strong dissolution, poor core recovery and intense core disturbance have masked the biostratigraphy or magnetostratigraphy over some intervals of all recovered sections. DSDP Leg 73 results show the following correlations:

Early/middle Miocene       in Chron 16
Oligocene/Miocene           within Subchron C6N
Eocene/Oligocene            within Subchron C13R
Middle/late Eocene           top of Chron C17
Early/late Paleocene         top of Subchron C27N
Cretaceous/Tertiary          within Subchron C29R
