Investigating the Plate Kinematics of the Bay of Biscay Using Deformable Plate Tectonic Models

“…A uniform 30 km crustal thickness estimate at 270 Ma was also chosen for this deformable plate model. An initial 30 km crustal thickness estimate was considered for all deformable models and was chosen to capture potential minor crustal thinning caused by Triassic rifting over the continental shelves adjacent to the Bay of Biscay (Cadenas et al., 2020; De Charpal et al., 1978; Montadert et al., 1979; Ruffell, 1995). Due to the longer runtime for model 2, it experienced more thinning than the other four models.…”

“…In addition, another scenario not captured by model 5 is the potential role of Permian to Early Liassic rift basins within the English Channel that may have previously thinned the crust as a result of intracontinental rifting (Ruffell, 1995). Model 2 was the only deformable plate model that included Late Permian-Triassic related deformation.…”
