Abstract

The Neogene stratigraphic succession beneath the continental shelf off New Jersey is evaluated using high-quality seismic and well data. Seismic sequence analysis and interpretation of stratal stacking patterns in well logs indicate that the observed depositional sequences can be subdivided into lowstand and highstand systems tracts. Sandstone beds occur in association with two distinct seismic facies. The first type compose the topset and toplapping beds of prograding depositional systems, typically highstand systems tracts. The second type of sandstone is present at the toes of depositional slopes, where it onlaps against prograding deltaic wedges. The observed geometry and lithofacies distribution of the Neogene depositional sequences are compared to the "standard' Exxon sequence stratigraphic model. Paleontologic data bracket the ages of the individual sequences but are not detailed enough at present to correlate precisely to the time scale and inferred global sea-level records. Neogene depositional sequences from offshore New Jersey have a cyclicity consistent with interpeted third-order eustatic fluctuations on the global cycle chart. -from Authors
