Main active faults in the Granada and Guadix-Baza Basins (Betic Cordillera)

Climatic control on palaeohydrology and cyclical sediment distribution in the Plio - Quaternary deposits of the Guadix Basin ( Betic Cordillera , Spain )

A cyclical pattern can be observed in the central sector of the Guadix Basin (southern Spain) in the Late Pliocene-Quaternary alluvial fan deposits prograding into its axial valley. A climatic significance has been attributed to this cyclicity on the basis of sedimentological and preliminary isotopic studies. The progradation phases of the alluvial fans are here attributed to more arid time int...

Recent Tectonic Structures in a Transect of the Central Betic Cordillera

The Betic Cordillera has undergone recent Alpine deformations related to the EurasianAfrican plate interaction boundary. Most of the present-day relief has been built up since Tortonian times, and is related to the development of folds and faults that are overprinted on older deformations, and some of the faults may be considered as out-of-sequence. The combination of geophysical and geological...

Late Miocene – Pleistocene tectono - sedimentary evolution and subsidence history of the central Betic Cordillera ( Spain ) : a case study in the Guadix intramontane basin

Exhumation of high-pressure metapelites and coeval crustal extension in the Alpujarride complex (Betic Cordillera)

The current configuration of the Alpujarride complex (Befic Orogen) comprises a stack of thinned tectonic units, made up mainly of continental crest. P T path modelling in different levels of an Alpujarride unit (the Salobrefia tectonic unit) reveals a high-pressure metamorphic stage followed by subsequent decompression at nearly isothermal conditions. Nevertheless, the P T conditions differ fr...

Timing of tectonic events in the Alpujárride Complex, Betic Cordillera, southern Spain

Ar–Ar and fission-track dating from four low-grade sections in the Alpujárride Complex sheds light on the timing of the early contractional history of these high-pressure metamorphic units, and their subsequent exhumation during the early Miocene extensional collapse of the Betic orogen. White mica grains from the lowest-grade rocks yield partly reset detrital Ar–Ar ages; where deformation and ...
