| Abstract | Five formations have been distinguished in the Miocene stratigraphic record of the Mencal area (Central Betic Cordillera). The two lowermost ones, Canada andAlmidar Formations, Oligocene - early Burdigalian in age, represent the last deposits of the South-lberian Palaeomargin. The two following ones, Moreda andAguila Formations, dated as late Burdigalian- middle Serravallian, were deposited in the North-Betic Foreland Basin. The uppermost Reefal Formation, late Tortonian in age, characterizes the beginning of the Intramontane Guadix Basin deposition. The limits between the four upper stratigraphic units correspond to majar tectosedimentary events in the palaeogeographic evolution of the North-Betic Foreland Basin. The most outstanding event recorded, known as Burdigalian Paroxysm, brought about the configuration of the North-Betic Foreland Basin and the whole disarrangement of the South-Iberian Palaeomargin. As a consequence of this event, the units belonging to this palaeomargin, together with others from the Alboran Block, constituted an active front located to the south ofthe foreland basin. The sedimentary evolution ofthe North-Betic Foreland Basin is controlled by three phases of advance and one of stabilization of this active front. Two first advance phases, Finiburdigalian and Finilanghian events, are connected to sudden episodes of flexural subsidence and basin deepening. The stabilization phase, Intralanghian event, is recorded by an episode of uplift and shallowing. The evolution of the basin finishes with the last tectonic advance phase, Finiserravallian event, giving rise to the emersion of most of the basin and its subsequent incorporation to the active front. After this last event the North-Betic Foreland Basin became two independent palaeogeographic basins: the Guadalquivir Basin and the lntramontane Guadix Basin. |
