根据对巴利阿里盆地、科西嘉-撒丁岛地块、北部第勒尼安海和北部亚平宁地区的地层和构造数据的修订，对位于萨丁岛-科西嘉-普罗旺斯和北亚平宁地区之间的地区提出了以下新的假设：(A)从晚白垩世开始，随着洋壳在伊比利亚板块之下俯冲而汇聚；(B)渐新世-阿基坦期大陆碰撞，发展了北部亚平宁地块，并在由科西嘉-撒丁尼亚地块组成的腹地(仍附着于伊比利亚板块)发生海侵变形；(C)在缅甸，构造体制从挤压转变为伸展。在此期间，科西嘉-撒丁岛地块与巴利阿里盆地、撒丁岛裂谷和第勒尼安海北部的开放同时迁移；(D)从布隆迪到现在，亚平宁北部链的前部有同期的挤压，后部有伸展；这两个特征都逐渐向东迁移。同时代的伸展和挤压归因于岩石圈向带外部的拆沉作用。
Based on a revision of stratigraphic and structural data relative to the Balearic basin, the Corsica-Sardinia massif, the Northern Tyrrhenian Sea and the Northern Apennines the following new hypothesis is proposed for the area located between the Sardinian-Corsican-Provencal and Northern Apennines regions: (a) convergence with subduction of oceanic crust under the Iberian plate beginning in the Late Cretaceous; (b) continental collision in the Oligocene-Aquitanian, with development of the Northern Apennines belt and transpressive deformation in a hinterland that consisted of the Corsica-Sardinia massif (still attached to the Iberian plate); (c) in the Burdigalian the tectonic regime changed from compressive to extensional. During this period the Corsica-Sardinia massif migrated contemporaneously with opening of the Balearic basin, the Sardinian rift, and the Northern Tyrrhenian sea; (d) from the Burdigalian to the present, there was contemporaneous compression at the front and extension at the back of the Northern Apennines chain; both these features progressively migrated toward the east. The coeval extension and compression is attributed to lithospheric delamination toward the external part of the belt.
