DescriptionThis thesis uses seismic-sequence-stratigraphic analysis to show the stratigraphic development of the northern Nova Scotia passive margin (the Laurentian Subbasin) during the Cretaceous through Paleogene. It documents the interplay of several variables on margin evolution including changes in relative sea-level, sediment supply, and tectonic activity including thermoflexural subsidence and salt movement. Salt structures, basement-involved deformation, and sparse well control impede the interpretation of stratigraphic patterns in the study area. Despite these difficulties, I have identified eight candidate sequence boundaries using seismic-reflection terminations: (1) top-lap and
truncation below a discontinuity, and (2) on-lap and down-lap above a discontinuity.
Study of the sequence stratigraphy in the Laurentian Subbasin reveals two significant unconformities, the Jurassic-Cretaceous (Avalon) unconformity and the
Cretaceous-Paleogene (KP) unconformity, and seven sequences: three Cretaceous sequences (Sequences 1, 2, and 3) and four Paleogene sequences (Sequences 4, 5, 6 and 7). Change in relative sea level and sediment-supply directions during the Cretaceous are not well documented. Salt tectonics and thermoflexural subsidence created the accommodation space for the Early Cretaceous sequences. System tracts controlled by relative sea-level change show that sediment supply was from the northwest and
depocenters migrated from northeast to southeast during the Paleogene.
Comparison of the Baltimore Canyon Trough with the Laurentian Subbasin shows that these basins in the passive margin of eastern North America have similarities and differences. The similarity includes the presence of clinoform geometries above the KP
boundary indicating aggradational-progradational stratigraphic patterns. The differences include the major Jurassic-Cretaceous (JK) unconformity, the presence of salt structures, and the presence of Paleogene sequences. In the Scotian Basin, the JK unconformity is a major angular unconformity (Avalon unconformity) separating gently dipping Cretaceous
rocks above from folded Jurassic rocks below. However, the JK unconformity in the Baltimore Canyon Trough generally is a paraconformity separating subparallel beds above and below the unconformity.
