La subsidencia tectónica en la Cordillera Ibérica durante el Mesozoico

La subsidencia tectónica en la Cordillera Ibérica durante el Mesozoico

Abstract

Las trayectorias de subsidencia se construyen con datos de dos áreas de la Cordillera Ibérica. Ambas curvas muestran dos ciclos de subsidencia tectónica. La primera (Triásico-Jurásico) pertenece al desarrollo de celtíberos aulacógenos, en relación con el margen pasivo Bético Balear (Tetis occidental). El segundo ciclo tuvo lugar en tiempos del Cretácico, y fue condicionado por el desplazamiento en el sentido opuesto a las agujas del reloj de la placa Ibérica y la apertura del Golfo de Vizcaya. El índice de estiramiento era de bajo a moderado: 1.12 y 1.26.

The subsidence trajectories are built with two localities data from the Iberian Chain. Both curves show two rifting-tectonic subsidence cycles. The first one (Triassic-Jurassic) belongs to the development of the Celtiberian Aulacogen, in relationship with the BeticBalearic passive margin (Western Tethys). The second cycle occurred in Cretaceous times, and it was conditioned by the Iberian Plate anti-clockwise drifting and Bay of Biscay openning. The stretching rates were Iow to moderate: 1.12 and 1.26.
