Biofacies analysis of benthic foraminifera and planktonic foraminiferal and calcareous nannofossil biostratigraphy in upper Paleocene to middle Eocene formations in the New Jersey coastal plain are used to identify depositional sequences and to correlate them with the third-order cycles of Haq and others (1987). Two sequences separated by hiatuses are identified in the upper Paleocene and correlated with cycles TA2.1 and 2.3.
Three sequences are recognized in the lower Eocene and correlated with cycles TA2.4-2.5, 2.7-2.8, and 3.1 Hiatuses separating these sequences in the lower Eocene correlate with type 1 unconformities on the Haq and others (1987) cycle chart. The hiatus corresponding to the type 1 unconformity between cycles TA2.9 and 3.1 on the cycle chart is also recognized in DSDP sites 605 and 613.
Three sequences are delineated in the middle Eocene. They correlate respectively with cycles TA3.3, 3.4, and 3.5-3.6 and are separated by hiatuses.
Paleoslope modeling indicates that relative sea level stood between 55 m and 120 m above present sea level during deposition of transgressive deposits in the New Jersey coastal plain. The shoreline would have shifted about 70 km during this change.
