Resumen

Integration of stress indicator data, gravity data,
crustal kinematics data, and analysis of topography and
recent vertical motions demonstrates the occurrence of
consistently oriented spatial patterns of large-scale
Alpine to recent intraplate deformation in Iberia. The
inferred upper crustal and lithospheric deformation
patterns and the timing of the associated expressions
at or near the surface support the existence of a close
coupling with plate boundary processes operating at
the margins of Iberia. Patterns of lithosphere and
upper crustal folds are oriented perpendicular to the
main axis of present-day intraplate compression in
Iberia inferred from structural analysis of stress
indicator data and focal mechanism solutions. These
findings suggest the presence of lithospheric folds,
with wavelengths compatible with theoretical
predictions of folding wavelengths of Variscan
lithosphere. Stress-induced intraplate deformation
set up by plate interactions is compatible with
indications for the absence of present-day deep
mantle-lithosphere interactions inferred from seismic
tomography.
