Subduction and Slab Detachment in the Mediterranean-Carpathian Region
M. J. R. Wortel,Wim Spakman +1 more
TL;DR: Seismic tomography models of the three-dimensional upper mantle velocity structure of the Mediterranean-Carpathian region provide a better understanding of the lithospheric processes governing its geodynamical evolution.
Journal ArticleDOI
Lateral slab deformation and the origin of the western Mediterranean arcs
TL;DR: In this article, the authors describe the evolution of the western Mediterranean subduction zone (WMSZ) during the last 35 Myr by combining new and previous geological data, new tomographic images of the Western Mediterranean mantle, and plate kinematics.
Journal ArticleDOI
P wave tomography of the mantle under the Alpine-Mediterranean area
Claudia Piromallo,Andrea Morelli +1 more
TL;DR: In this article, the authors study the upper mantle P wave velocity structure below the Euro-Mediterranean area, down to 1000 km depth, by seismic travel time tomography, and obtain about 26% root-mean-square (RMS) reduction of residuals by inversion in addition to roughly 31% reduction after summary rays formation and selection.
Journal ArticleDOI
Deep roots of the Messinian salinity crisis
TL;DR: Using a thermomechanical model, it is shown that westward roll back of subducted Tethys oceanic lithosphere and associated asthenospheric upwelling provides a plausible mechanism for producing the shift in magma chemistry and the necessary uplift along the African and Iberian continental margins to close the Miocene marine gateways, thereby causing the Messinian salinity crisis.

Kinematics of the Western Africa-Eurasia plate boundary from focal mechanisms and GPS data
Enrico Serpelloni,Gianfranco Vannucci,S. Pondrelli,Andrea Argnani,Giuseppe Casula,Marco Anzidei,Paolo Baldi,Paolo Gasperini +7 more
TL;DR: In this article, the authors used earthquake and Global Positioning System (GPS) data to study the present-day kinematics and tectonics of the Africa-Eurasia plate boundary in this region.

Traveltimes for global earthquake location and phase identification
Brian Kennett,E. R. Engdahl +1 more
TL;DR: The Iasp91 traveltime tables as mentioned in this paper are derived from a radially stratified velocity model which has been constructed so that the times for the major seismic phases are consistent with the reported times for events in the catalogue of the International Seismological Centre (ISC) for the period 1964-1987.

Generalized Nonlinear Inverse Problems Solved Using the Least Squares Criterion
Albert Tarantola,Bernard Valette +1 more
TL;DR: In this article, a general definition of the nonlinear least squares inverse problem is given, where the form of the theoretical relationship between data and unknowns may be general (in particular, nonlinear integrodierentia l equations).
Journal ArticleDOI
Kinematics of the western Mediterranean
TL;DR: In this article, a preliminary model for the Cenozoic kinematic evolution of the western Mediterranean oceanic basins and their peripheral orogens is presented, which integrates the motion of Africa relative to Europe based upon a new study of Atlantic fracture zones using SEASAT data and the Lamont-Doherty magnetic anomaly database.
Journal ArticleDOI
Closing the gap between regional and global travel time tomography
TL;DR: In this article, the authors employed an irregular grid of nonoverlapping cells adapted to the heterogeneous sampling of the Earth's mantle by seismic waves to resolve lateral heterogeneity on scales as small as 0.6° and 1.2°.
Journal ArticleDOI
Convective instability of a thickened boundary layer and its relevance for the thermal evolution of continental convergent belts
TL;DR: In this article, the authors studied the instability of a boundary layer for a range of physical parameters (Rayleigh number, amounts of thickening, and boundary conditions) and derived expressions that related the growth of the instability and the time needed to remove the boundary layer as a function of the amount of horizontal shortening (f), the Rayleigh number (R), and the ratio (a/d) of the thicknesses of the rigid and fluid layers.
