Resumen
The Alpujarride/Nevado-Filabride boundary exposed in the Sierra Alhamilla is a detachment fault belonging to the Fiiabres Extensional System (FES), a pronouncedly asymmetric system with a westsouthwestward transport direction. It was active during the Serravallian and folded during the Upper Tortonian-Messinian times. The FES geometry suggests a complex extensional history with more than one episode of norm al faulting. There are listric fans coalescing to a floor fault at shallow le vels and extensional duplexes at the deeper ones. The duplexes formed by migrating footwall faults, horses being bounded by out-of-sequence faults and inactive tilted faults belonging to the overlying listric fans
