Present-day dynamics of the Aegean region: A model analysis of the horizontal pattern of stress and deformation

Article Abstract:

A forward model approach is adopted to gain insight into forces controlling current stress field and pattern of horizontal motions in the Aegean region. A thin elastic shell representation of the Aegean lithosphere is used to calculate stress field and displacements linked with force sets, which are compared with state of stress observations based on fault kinematics. Mechanisms believed to control the Aegean tectonics are the force exerted by the Anatolian block and that associated with the Hellenic subduction zone.

Shallow slab detachment as a transient source of heat at midlithospheric depths

Article Abstract:

Research into the breakoff process and the following thermal development of a plate boundary region involving continental collision following an extended period of oceanic lithosphere subduction is presented. It is concluded that shallow slab detachment presents the opportunity for asthenospheric material to rise to depths as shallow as 35 km.

An early Pliocene uplift of the central Apenninic foredeep and its geodynamic significance

Article Abstract:

Issues concerning Plio-Pleistocene vertical motions of the central Apenninic inner forearc are discussed. It is suggested that the lateral reorganization of the central Apenninic forearc and the neighbouring part of the southern Apenninic forearc began between 4.4 Ma and 4.1 Ma.
