La transgresión Aptiense en la Sierra de Segura (Zona Prebética, provincia de Jaén)
The cretaceous successions of the Prebetic; deposited on the Southern Iberian Continental Margin, record the later part of a rifting stage (Oxfordian to early Albian). The northern part of the sierra de Segura (jaén province, SE Spain) shows a stratigraphic record of the tectonosedimentary evolution...

The cretaceous successions of the Prebetic; deposited on the Southern Iberian Continental Margin, record the later part of a rifting stage (Oxfordian to early Albian). The northern part of the sierra de Segura (jaén province, SE Spain) shows a stratigraphic record of the tectonosedimentary evolution of the early cretaceous time. Four sedimentary sequences have been defined for the Barremian - Early Albian interval, which are evidence for different transgressive pulses, coinciding with the extensional phases of the north atlantic rifting. The first transgressive episode took place in the early Barremian, with deposition of several marine carbonate beds within a lacustrine succession (sequence 04). In the late Bedoulian arose the maximum transgression, with deposition of litoral calcarenites in previously emerged areas of the margin (sequence Ci5). The concluding reactivation of the rifting phase occurred in the late Aptian, with deposition of rudist-bearing limestones in all the studied area (sequence 06).
