abstract = {We obtain P-wave receiver functions from teleseismic earthquake recordings at a dense seismic broadband
transect, deployed along 170 km across the Betic mountain range in southeastern Spain.
Migrated images show the crustal structure of the orogen in detail. In particular, they reveal the situation
of the subducted Iberian paleomargin, with full preservation of the proximal domain and the  50 km
wide necking domain. Crustal thinning across the necking domain affects mainly the lower continental
crust. The Variscan crust of the Tethys margin is bending downward beneath the Betics, reaching
 45 km depth, and terminates abruptly at a major slab tear. The distal domain of the paleomargin cannot
be reconstructed, but the migrated section suggests that material has been exhumed through the subduction
channel and integrated into the Betic orogen. This supports an origin of the HP-LT Nevado-Filabride
units from subducted, hyperextended Variscan crust. According to our profile, the present-day eastern
Betics appear to have a much more significant contribution from metamorphic Iberian crust than previously
thought.},
