Abstract
El graben asimétrico de Albuñuelas se localiza en el extremo sureste de
la cuenca intramontañosa de Granada. Su estructura se define por un sistema de fallas normales E-O que hunden el bloque de depósitos
sedimentarios neógenos y que intersectan con un sistema de pliegues asimétricos vergentes al norte. Los rasgos estructurales observados permiten
reconstruir la evolución del graben asimétrico y vincularla a la evolución geológica regional de la Cordillera Bética. Los datos interpretados de los perfiles
de los ríos y de los sedimentos recientes cerca de la falla principal sur (Falla
de Albuñuelas) sugieren revisar su actividad
The Albuñuelas asymmetric graben is located in the southeastern end of the Granada intramontane basin. Its structure is defined by a conjugate system of E-W normal faults that down-drop the Neogene sedimentary deposits and cross-out a system of north-vergent asymmetric folds. The observed structural features allow the reconstruction of the asymmetric graben evolution and its linkage to the regional geologic evolution of the Betic Chain. The interpreted data from the river profiles and the recent sediments related to the main southern fault (Albuñuelas Fault) suggest the need of revision of its activity
