The NW-SE trending Northern Apennine Mountains consist of a series of allochthonous units which were thrust generally to the NE during Neogene crustal shortening, in the direction of a foreland basin to the east and NE.

Abstract
The NW-SE trending Northern Apennine Mountains consist of a series of allochthonous units which were thrust generally to the NE during Neogene crustal shortening, in the direction of a foreland basin to the east and NE. On the hinterland (internal) side of this fold-and-thrust belt, a series of small-scale sedimentary basins developed from the late Miocene and were deformed at the same time. The late Tortonian-Pleistocene evolution of the Northern Apennines has previously been considered by most authors in terms of a classical model of a NE-migrating compressional front, which was followed in time and space by a hinterland extensional regime related to the development of the Tyrrhenian Basin. This paper presents new structural data from both the external parts of the Northern Apennines and the late Tortonian-Pleistocene basins located in the internal sector. In the Northern Apennine thrust belt, reactivation and out-of-sequence geometries for the thrust faults have been recorded.File | Dimensione | Formato | |
