Tectonics of the West Iberia continental margin from seismic reflection data
… component of the plate tectonic cycle. The West Iberia passive margin is a classic example of a nonvolcanic rifted margin. The West Iberia margin contains an enigmatic north-south ridge of serpentinized peridotite located within the ocean-continent transition. Interpretation of multichannel …

Mechanisms of late-stage rift deformation: evidence from new 3D seismic data over the West Iberia margin
I describe a new 3D seismic dataset over the West Iberia margin that demonstrates the complex 3D architecture of hyperextended continental crust and exhumed continental mantle at the distal edge of the margin. Faulted continental crustal blocks show higher degrees of extension in the north than the …

Neoproterozoic to Holocene tectonothermal evolution of the southern Cantabrian Mountains NW Iberia, revealed by apatite fission-track thermochronology
… renewed tectonic activity along the northern Iberian margin, climaxing by latest Miocene (Messinian) time. Heterogeneous cooling of samples is evidenced from Early Pliocene time. Post-tectonic denudation is interpreted to have become the dominant infl uence of cooling in the study area. In …

Understanding the selection and co-existence of tin bronze alloying techniques in Antiquity. An experimental and archaeological approach with Northeast Iberia as case study (2800-200BC).
… of archaeological assemblages from Northeast Iberia dated between Chalcolithic and Iberian times (2800-200BC) are presented. Archaeometallurgical by-products of these collections were analysed using pXRF, OM, SEM-EDS, and LIA to characterise technological choices through time. These choices …

Chromosomal inversions as a mechanism for sympatric differentiation in common quails
… In Chapter 1, quails wintering in southern Iberia are analysed to determine the genetic composition of the wintering population and to test whether the presence of overwintering individuals reflects potential spatial segregation linked to the chromosome 1 inversion, these analyses reveal …

High-resolution temporal records of magmatism, sedimentation, and faulting at evolving plate boundaries
… the rift-to-drift transition in the Newfoundland-Iberia rift. This rift is considered the type example of a magma-poor rifted margin and both margins consist of broad areas of exhumed subcontinental lithospheric mantle. Chapter 5 documents time-transgressive magmatism from east to west across both …
