Abstract
La modelización matemática del evento catastrófico que puso fin a la crisis
de salinidad del Messiniense se ha integrado con los elementos geomorfológicos
definidos en la superficie del techo del Messiniense en base al estudio
de una densa red de perfiles sísmicos localizada en el Estrecho de Gibraltar
y en el Mar de Alborán. La integración de la cartografía de los elementos
geomorfológicos, como terrazas y un gran surco erosivo que atraviesa
toda la cuenca de Alborán, con las cinco fases de la inundación del
zancliense (0 a 4) determinadas por el modelo matemático, ha permitido
una mayor precisión en la interpretación y el establecimiento de la cronología
de los procesos relacionados con la inundación. Igualmente, esta integración
permite cuantificar la magnitud de la inundación, la cual hubiera
sido difícil de inferir solo a partir de las evidencias geomorfológicas
The mathematical modeling of the catastrophic event that put an end to the Messinian Salinity Crisis is integrated with the geomorphological features defined on the Messinian top surface, based on the analysis of a dense net of seismic profiles surveyed in the surroundings of the Strait of Gibraltar and Alboran Sea. The mapped morphosedimentary features as terraces and great erosive channel that crosses the entire Alboran basin coupled with the five Zanclean flooding phases (0 to 4) of the mathematical model, have allowed a more precise interpretation and timing of the geological processes related to the flooding. Likewise, this integration permits quantifying the catastrophic magnitude of that flooding which had been difficult to infer from the geomorphological evidences
