Description
Summary:•Lack of evidence to support a counterclockwise rotation of the Piñon block and the coeval opening of the Progreso Basin.•Forearc basin controlled by the complex interplay of oblique subduction, rise of an outer forearc high, and tectonic escape.•Post-accretion strain partitioning across an outer wedge with a varying trench-parallel oriented deformation.
