| Summary: | The Nova Scotia passive continental margin is characterized by longitudinal variation in crustal structure from the volcanic U.S. Atlantic Margin in the southwest to a non-volcanic Newfoundland Margin in the northeast. The objectives of this study include characterizing the tectonic structure of the margin and analyzing the interconnected processes of extension, thermal subsidence, compaction, and isostatic response that contribute to the margin's tectonic evolution. In this study, 2D structural seismic interpretation integrated with published bathymetry, magnetic, and gravity surveys is carried out to characterize the tectonic structure of the margin. The 2D kinematic restorations along NW-SE cross-sections are conducted to quantify the variations in the amount of tectonic extension, subsidence, accommodation, isostatic response and compaction across and along the margin and compare how different crustal structural styles and salt kinematics affect these variations through time.
