Description:
DSDP Leg 73 sediment cores allow direct calibrations of magnetostratigraphy and biostratigraphy for much of the latest 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 C6CN
Eocene/Oligocene within Subchron C13R
Middle/late Eocene top of Chron C17
Early/late Paleocene top of Subchron C27N
Cretaceous/Tertiary within Subchron C29R
