Palaeomagnetic constraints on the geodynamic evolution of the Gibraltar Arc

Terra Nova, 2004
AbstractSubduction zone roll‐back was recently put forward as a convincing model to explain the geometry and evolution of the Gibraltar Arc. For other subduction‐related arc systems of the Mediterranean, such as the Calabrian Arc and the Hellenic Arc, palaeomagnetic rotation data from Neogene extensional basins provided important constraints on ...

Testing oceanic subduction and convective removal models for the Gibraltar arc: Seismological constraints from dispersion and anisotropy [PDF]

Tectonophysics, 2011
We discuss mantle structure and dynamics under the Gibraltar arc. For that region, a large variety of geodynamic models has been proposed, and there was, up to recently, no consensus on which of these models is the best one to describe the geodynamic situation of the region.

P-wave velocities of the upper mantle of the Tethysalpine geosynclines

Геофизический журнал, 2020
The aim of the work is to calculate the velocity distribution of the longitudinal seismic waves (VP) in the upper mantle at depths from the discontinuity M to 400 km.

Seismic anisotropy beneath southern Iberia from SKS splitting [PDF]

, 2008
International audienceSeismic anisotropy of the south Iberian upper mantle is investigated using shear-wave splitting of SKS phases. We analyzed teleseismic events recorded by sixteen permanent broadband stations installed on the southern Iberian ...

Relative landscape maturity in the South Rifian Ridges (NW Morocco): Inferences from DEM-based surface indices analysis

Applied Computing and Geosciences, 2020
In this paper we present the first landscape maturity analysis of the South Rifian Ridges, part of the southern branch of Gibraltar Arc (Morocco). Since the late Miocene, the southward propagation of anticlines structures is driven by the convergence ...

The mediterranean overflow in the Gulf of Cadiz: a rugged journey [PDF]

, 2017
The pathways and transformations of dense water overflows, which depend on small-scale interactions between flow dynamics and erosional-depositional processes, are a central piece in the ocean's large-scale circulation.

Crustal thickness and images of the lithospheric discontinuities in the Gibraltar arc and surrounding areas [PDF]

Geophysical Journal International, 2015
The Gibraltar arc and surrounding areas are a complex tectonic region and its tectonic evolution.since Miocene is still under debate. Knowledge of its lithospheric structure will help to.understand the mechanisms that produced extension and westward motion of the Alboran domain,.simultaneously withNW–SE compression driven by Africa–Europe plates ...

Seismic source in the Iberian-African plate boundary [PDF]

, 2003
The plate boundary between Iberia and Africa has been studied using data on seismicity and focal mechanisms. The region has been divided into three areas: A; the Gulf of Cadiz; B, the Betics, Alboran Sea and northern Morocco; and C, Algeria.

The Lithospheric Structure of the Gibraltar Arc System From Wide‐Angle Seismic Data [PDF]

Journal of Geophysical Research: Solid Earth, 2020
AbstractIn continental settings, seismic failure is generally restricted to crustal depth. Crustal structure is therefore an important proxy to evaluate seismic hazard of continental fault systems. Here we present a seismic velocity model across the Gibraltar Arc System, from the Eurasian Betics Range (South Iberian margin), across offshore East ...

Quantification of Erosion and Uplift in a Rising Orogen—A Large-Scale Perspective (Late Tortonian to Present): The Case of the Gibraltar Arc, Betic Cordillera, Southern Spain

Remote Sensing, 2020
The present study deals with the morphometric quantification of erosion and illustrates the uplift component triggered by denudation (isostasy) in the growth and evolution of a rising orogeny by the application of Airy isostasy concepts.
