Abstract: Late Cretaceous magmatism on the West Iberian Margin is widespread and extends offshore onto a larger province, which on the Estremadura Spur includes the evidence of a > 20 km long laccolith (the Estremadura Spur Intrusion), the Fontanelas volcano and its associated plumbing systems, as observed on high-resolution seismic data. The integrated seismic-stratigraphic and structural analysis of the post-rift sequences allows to reveal that multiple tectono-magmatic events have resulted in decoupled deformation of the Cretaceous to Tertiary strata, ultimately allowing to establish the timing, magnitude and distribution of inversion.
