Revisiting the Appalachian structural front and offshore Anticosti Basin (northern Gulf of St. Lawrence, Canada) by integrating old and new geophysical datasets

The Anticosti Basin is a large, predominantly marine sedimentary basin centered within the northern Gulf of St. Lawrence. Poor-quality vintage seismic reflection data collected more than 25 years ago in the offshore part of the basin failed to depict its geometry. However, recently acquired multibeam bathymetry and magnetic data can be used in combination with high-resolution seismic lines to map the Paleozoic succession within the Honguedo …
