摘要
It is widely believed that the Africa-Eurasian relative motion in the Mediterranean region is oriented SE-NW to S-N. This result has been deduced from the analysis of North Atlantic kinematic data by assuming that Eurasia is a unique coherent plate from the North Atlantic ridges to the Pacific trenches. However, this assumption cannot easily account for the not negligible tectonic activity inside and around Western Europe (Rhine Graben system, Pyrenees and off-short Portugal). This paper shows that, if one allows Western Europe to move independently from main Eurasia, the kinematic indicators in the North Atlantic do not exclude other kinematic solutions which are significantly different from those currently accepted. In particular, it is demonstrated that a SSW-NNE to SW-NE trending Africa-Eurasia convergence, beside allowing plausible explanations of major post-Tortonian deformation events in the Central Mediterranean region, can fit North Atlantic data within experimental errors.
