“…Previous studies have found some evidence of £uvial deposits across the New York^Washington, DC corridor that correlate to lower Miocene marine sequences. Pazzaglia (1993) and Pazzaglia & Gardner (1993, 1994 have described the Bryn Mawr Formation, a £uvial terrace deposit that crosses Maryland, Delaware and Pennsylvania and consists of three separate cycles ranging from late Oligocene to late Miocene. Each cycle represents a third-order (1^10 Myr) marine transgressive event.…”

“…Posamentier & James (1993) and Christie-Blick & Driscoll (1995) suggested that sequence stratigraphy is not a rigid discipline to be forced on all sedimentary basins.There are no set rules requiring the occurrence of all systems tracts of speci¢c geometry and thickness on all seismic pro¢les. Local conditions must be considered in de¢ning internal stratal patterns (Martinsen, 1994;Martinsen & Helland-Hansen, 1995). For example, previous studies of the New Jersey margin (Metzger et al, 2000;Pekar et al, 2001) highlighted variations on the standard model and concluded that Lowstand SystemsTract (LST) deposits were absent from the coastal plain (see summary in Browning et al, this volume).…”

Early Miocene sequence development across the New Jersey margin

Sequence stratigraphy provides an understanding of the interplay between eustasy, sediment supply and accommodation in the sedimentary construction of passive margins. We used this approach to follow the early to middle Miocene growth of the New Jersey margin and analyse the connection between relative changes of sea level and variable sediment supply. Eleven candidate sequence boundaries were traced in high‐resolution multi‐channel seismic profiles across the inner margin and matched to geophysical log signatures and lithologic changes in ODP Leg 150X onshore coreholes. Chronologies at these drill sites were then used to assign ages to the intervening seismic sequences. We conclude that the regional and global correlation of early Miocene sequences suggests a dominant role of global sea‐level change but margin progradation was controlled by localized sediment contribution and that local conditions played a large role in sequence formation and preservation. Lowstand deposits were regionally restricted and their locations point to both single and multiple sediment sources. The distribution of highstand deposits, by contrast, documents redistribution by along shelf currents. We find no evidence that sea level fell below the elevation of the clinoform rollover, and the existence of extensive lowstand deposits seaward of this inflection point indicates efficient cross‐shelf sediment transport mechanisms despite the apparent lack of well‐developed fluvial drainage.

“…In the Eastern Barents Sea, the Upper Jurassic–Lower Cretaceous succession consists of 2 second‐order sequences and 7 third‐order sequences (Galloway, 1989; Nystuen, 1998). The second‐order sequences are divided into: (1) the Upper Jurassic–Barremian, and (2) the Barremian–Cenomanian.…”

The Upper Jurassic–Lower Cretaceous sedimentary rocks in the Eastern Barents Sea Basin are up to 2 km thick and represent one of the least studied Arctic intervals. Here, for the first time, we present a detailed analysis of 43,000 km of 2D seismic profiles, as well as well‐log and core data from 24 offshore wells with the aim to create a comprehensive sequence stratigraphic framework that can be integrated with the rest of the basin. Results show that (1) seven third‐order sequences and five types of clinoforms can be identified based on integrated seismic and well data. The age of each sequence was established based on published biostratigraphic investigations along with new dinocyst interpretations included in this study; (2) the deep marine basin was gradually filled with sediments coming from north, east and south as a response to HALIP, Canada Basin opening and Cimmerian uplift of Novaya Zemlya, and was preserved only in the south‐western part of the Barents Sea Basin at the end of Early Cretaceous and (3) both Eastern Barents Sea and West Siberia Basin share similarities in sedimentary environments and tectonic setting, though the spatial distribution of clastic reservoirs in Upper Jurassic and Lower Cretaceous mega‐sequence heavily depends on the source areas that require more provenance focused research. The results presented here can be used in further regional exploration in the area and to better understand the geodynamic evolution of the Greater Barents Sea Basin.
