Analyses of stratigraphic correlations, sedimentary facies, reservoir distribution, and structural settings of Mesozoic and Cenozoic sediments in the surface and subsurface of the Salisbury embayment are used to produce petroleum entrapment models for projection into the submerged part of the Atlantic continental margin geosyncline. Some correlations involve simple, long-range, widespread, uniform marine units; others deal with numerous abrupt facies changes in the marine and nonmarine sediments. Local minor unconformities are common at the margin of the geosyncline. Excellent reservoir conditions are found throughout the onshore stratigraphic section. A list of models thought to exist in the deeper subsurface of the Baltimore Canyon basin and the adjacent continental slo e-rise geosyncline has been compiled for use in future studies of the petroleum potential of the deeper Atlantic continental margin. These trap models are (1) factual--marine sand facies pinchouts, channel sands, sediment wedges under unconformities, local basement topography entrapments, basement fault zones; and (2) hypothetical--projected marine-nonmarine facies pinchouts, salt diapirs, structures of linear basement ridge, and turbidite sand entrapment on the continental slope-rise.
