Seismic sequence stratigraphy during the Cretaceous through the early Paleogene in the northern Scotian basin (Laurentian Subbasin) offshore Nova Scotia and Newfoundland, Canada:
This 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 relati...

This 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).
