Seismic and gravity anomaly evidence of large-scale compressional deformation off SW Portugal

Journal article

Multi-channel seismic and gravity anomaly data have been used to determine the extent of compressional deformation along the SW Portugal rifted continental margin and place constraints on the long-term (>1M.a.) strength of the lithosphere. The seismic sections suggest that the region of compressional deformation is broad (~100km) and has been active since the Miocene. Integration with recently compiled high-resolution bathymetric data shows that the main thrust front is located along the b...
