Gaspé Belt subsurface geometry in the northern Québec Appalachians as revealed by an integrated geophysical and geological study: 2 - Seismic interpretation and potential field modelling results

► The Gaspé belt results from the tectonic inversion of a former extensional basin ► Growth strata testify of normal motion during the Silurian to earliest Devonian ► Cross-sections integrate seismic data and are balanced for gravity and magnetism ► No efficient level of décollement ► A higher deformation zone is due to a vise effect between two basement blocks
