Abstract

Correlation of sedimentary rock thicknesses with radio-metric age dates permits identification of the occurrence of relatively rapid sedimentation on the mid-Atlantic margin of North America during late Aptian and (or) early Albian, Cenomanian, and Turonian time. To accommodate the sediment, the continental shelf experienced short periods of rapid strain. This activity was penecontemporaneous with phases of rapid sediment accumulation previously identified in cratonic basins; attention is drawn to the possible geodynamic significance of this apparent synchrony.
