Summary New palaeomagnetic data are consistent with the hypothesis that Adria moved as a promontory of the African Plate during the Mesozoic. This hypothesis is supported by regional facies analysis and by geophysical data from the eastern Mediterranean basins which indicate a continental lithosphere. However, the new data cast doubt upon the concept of a rigid, autochthonous African promontory remaining coherent during Alpine deformation. It is apparent that small-scale relative rotations have occurred during the Tertiary in areas which were previously considered authochtonous. Late-tectonic extensional basins, such as the Tyrrhenian Sea, are superimposed on the continent-continent collision suture and their growth is contemporaneous with thrusting in surrounding arcs. The very rapid evolution of the collision suture into a region of extension is due to a rapid lithospheric thinning process, such as catastrophic delamination of part of the mantle lithosphere. Such delamination would be most likely to occur very soon after a collision involving fast lithospheric thickening.

Tectonic evolution of arcuate mountain belts on top of a retreating subduction slab: The example of the Calabrian Arc

[1] In this paper, new paleomagnetic results from the Calabrian Arc are presented, together with a critical review of all paleomagnetic data collected in the last decades in southern Italy. Our study is focused on the upper Miocene to middle Pleistocene deposits of the Crati extensional basin, a sector of the arc where an abrupt change in the sense of paleomagnetic rotations is observed. Paleomagnetic data indicate that the Crati basin underwent a uniform clockwise (CW) rotation of about 15°-20°in its central and southern part, whereas the northern sector is organized in small-scale fault-bounded blocks, which rotated independently. We interpret this pattern of deformation as the evidence of the complex nature of this area, which represents the boundary between two domains characterized by opposite rotations: the southern Apennines, which rotated counterclockwise, and the Calabria and Sicily, which rotated CW. Integrating these new paleomagnetic data with paleomagnetic data from southern Italy, we reconstruct the history of paleomagnetic rotations through time. Paleomagnetic rotations highlight the peculiarity of the formation of the Calabrian Arc curvature and imply that either an oroclinal bending model or a progressive arc model cannot be simply applied to the Calabrian Arc formation. We describe a realistic tectonic-geodynamic model, where the progressive curvature of the Calabrian Arc is framed within the space-time evolution of the Ionian subduction system.

Recently, new data have been presented which imply that major block rotations took place in the Central Mediterranean during the Pleistocene, between 1.0 and 0.7 Ma. Kinematic solutions for the spatial and temporal distribution of rotational data in the Central Mediterranean such as oroclinal bending of the Calabrian Arc and rotation of the Adria Plate are being discussed. Phases of neotectonic rotations appear to be confined to distinct phases of contractions and compressive interplate stress. We present a model in which the middle Pleistocene rotations are caused by a distribution of deformation in the Central Mediterranean through strike-slip motions along a number of major shear zones which define a free boundary between the African and the Adria Plates. One of the main features is the Trans-Mediterranean Mobile Zone, which separates areas with opposite rotations. The timing of the rotations is compared to the evolution of volcanism, basin development, subsidence and uplift patterns, contractional tectonics and seismicity patterns. From this comparison we hypothesize that the Late Pliocene-Recent geodynamic evolution of the Central Mediterranean comprises the following three episodes: (1) A Late Pliocene arc migration episode shows drifting of the Calabrian block and spreading of the back-arc basin without the associated oroclinal rotations that were previously assumed in literature. (2) An Early Pleistocene contraction episode shows a gradual increase of compressive interplate stress, and culminates in a middle Pleistocene "stress release phase" which is associated with block rotations, transpressional tectonics and a rupturing of the subducted slab. (3) A Late Pleistocene-Recent restabilisation episode is characterized by rapid isostatic adjustments, with extensional collapse of the Apennine thrust-wedge and the Tyrrhenian back-arc area related to rebound of non-detached lithosphere remnants and sinking into the mantle of the detached slab.
