I have used >10,000 line-km of multichannel seismic-reflection profiles and 88 key boreholes to map 23 postrift Mesozoic and Cenozoic depositional sequences of the U. S. Middle Atlantic margin. From these data I infer that tectonic uplift was consistently a dominant force in determining the architecture and distribution of the sequences. Relative uplift among three primary source terrains directly determined the location of siliciclastic dispersal routes, rates of sediment accumulation, and the latitudinal position of associated offshore depocenters.
The principal role of sea-level change appears to have been to distribute and redistribute sediments once they reached the basin complex. Sea-level change was particularly effective during long-term rises and short-term falls, when it determined the bathymetric position of depocenters. A marked increase in sediment supply (triggered by source-terrain uplift), however, could mask the effects of short-term sea-level rise. Moreover, in the absence of tectonic uplift, major sea-level falls generally did not accelerate sediment accumulation.
Paleoclimatic shifts appear to have influenced deposition most effectively when associated with extreme conditions, such as extensive aridity or the buildup of continental ice sheets. But the relative amount of carbonate production on the continental shelves also was responsive to paleoclimatic change.

The collected volume begins with a brief perspective by one of the conveners, followed by articles in order of increasing stratigraphic age. Eustatic sea-level changes and tectonic warpings of basins are competing mechanisms for explaining many stratigraphic patterns. The model for sea-level changes should be developed first for a basin, since it is allocyclic and leads to a series of time bands in the strata. The residual effects should then be modeled for tectonic patterns affecting the depositional processes. Doing the reverse limits time constraints on the tectonic warping models and will blur the resolution of detailed time surfaces in the strata. Case histories of situations with both tectonic warping and time surfaces marked by sea-level events will lead to improved interpretations of earth history.
