Crustal structure of the central sector of the Betic Cordillera (SE Spain)
Article Abstract:
Seismic reflection, magnetometric, and gravimetric data allow the study of main features of crustal structure of the central sector of the Betic Cordillera, southeast Spain. The region shows a slightly thickened crust with an abrupt transition to the thin crust of the Alboran Sea along an E-W oriented narrow band, subparallel to the coast line. In the External Zones, compressive deformation was caused by the Neogene evolution of the mountain chain. Faulting dominated the Internal Zones up to the Quaternary. A geological model explains the recent evolution of crustal deformation.

Recent and present-day stresses in the Granada Basin (Betic Cordilleras): Example of a late Miocene-present-day extensional basin in a convergent plate boundary
Article Abstract:
The Recent and present-day stress state in the southeastern area of the Granada Basin and surrounding regions was analyzed, based on a combined study of the earthquake focal properties and paleostresses determined from Recent structures. Seismicity in the area is focused in the upper crust to a depth of 14-16 km in the southeastern Granada Basin, reaching up to 25 km to the SW. The majority of the activity is expected to be produced by high-angle and detachment faults. The Granada Basin crust appears to have undergone uplift since the Tornonian.

The role of extension in the Miocene denudation of the Nevado-Filabride Complex, Betic Cordillera (SE Spain)
Article Abstract:
The Nevado-Filabride Complex in the Internal Zone of the Beltic Cordillera, Southeastern Spain is a thrust sheet of Paleozoic graphite-bearing basement wit overlying metapelitic sequences. Fission track thermochronological analysis of the denudation of Navado-Filabride indicated the presence of rapid cooling which was spatially related to the tectonic contact with the Alpujarride Complex. Furthermore, the upper crustal extension of the Baltic Cordilleras lasted until the early Tortonian period.
