英文摘要: The desiccation of the Mediterranean during the Messinian salinity crisis (MSC) is one of the most intriguing geological events of recent Earth history. However, the timing of its onset and end, as well as the mechanisms involved remain controversial. We present a novel approach to these questions by examining the MSC from the Atlantic, but close to the Gibraltar Arc, analysing the complete Messinian record of the Montemayor-1 core of the Guadalquivir Basin (SW Spain). Flexural backstripping analysis shows a tectonic uplift trend that would have reduced the depth of the Rifian Corridors considerably. Nonetheless, the rate of tectonic uplift was insufficient to account for the close up of the corridors. At 5.97. Ma, a global cooling and associated glacioeustatic sea-level drop, estimated in 60. m, is observed. This would have been sufficient to restrict the Rifian Corridors and to trigger the MSC. The later flooding of the Mediterranean occurred during a sea-level rise associated with global warming during a stable tectonic period. We postulate a two-step flooding event: 1) A glacioeustatic sea-level rise during interglacial stage TG 11 (5.52. Ma) led to subtropical Atlantic waters entering the west-central Mediterranean through pathways south of the Gibraltar Strait, probably the Rifian Corridors. 2) A global sea-level drop at 5.4. Ma, that might have favoured intensification of regressive fluvial erosion in the Gibraltar threshold, along with the subsequent global sea-level rise would have generated the Gibraltar Strait leading to complete Mediterranean refilling during the earliest Pliocene. © 2013 Elsevier B.V.
