In recent years, the origin of the Betic‐Rif orocline has been the subject of considerable debate. Much of this debate has focused on mechanisms required to generate rapid late‐orogenic extension with coeval shortening. Here we summarize the principal geological and geophysical observations and propose a model for the Miocene evolution of the Betic‐Rif mountain belts, which is compatible with the evolution of the rest of the western Mediterranean. We regard palaeomagnetic data, which indicate… 
Extension in the Western Mediterranean
The Miocene is an essential period in the configuration of the present-day relief of the Betic Cordillera and the South Iberian continental margin, which determined the structure and evolution of the
Neogene tectonic evolution of the Betic Chain: Insights from paleomagnetic, structural analyses, and laboratory models
Based on a critical revision of the available structural and paleomagnetic data coupled with results from laboratory models on oceanic subduction, we suggest that the curvature of the Gibraltar Arc
An evaporite‐bearing accretionary complex in the northern front of the Betic‐Rif orogen
The Guadalquivir Accretionary Complex forms a largely oblique prism at the northern edge of the Betic‐Rif orogen, where Miocene sediments plus allochthonous evaporite‐bearing units were accreted
Is the northwestern Betic Cordillera mountain front active in the context of the convergent Eurasia–Africa plate boundary?
The present relief of the Betic‐Rif Cordillera has been mainly developed since the Late Miocene in the context of the Eurasia–Africa NW–SE oblique convergence and other interacting processes like
History of subduction and back‐arc extension in the Central Mediterranean
SUMMARY Geological and geophysical constraints to reconstruct the evolution of the Central Mediterranean subduction zone are presented. Geological observations such as upper plate stratigraphy, HP–LT
The Mediterranean Basins: Tertiary Extension within the Alpine Orogen — an introduction
Abstract The recent evolution of ideas on the Mediterranean region has been triggered by very active data acquisition over the last 15 years. Seismic tomography provides an unique view of mantle
Back arc extension, tectonic inheritance, and volcanism in the Ligurian Sea, Western Mediterranean
The Ligurian basin, western Mediterranean Sea, has opened from late Oligocene to early Miocene times, behind the Apulian subduction zone and partly within the western Alpine belt. We analyze the deep
Continental collisions and the origin of subcrustal continental earthquakes
The existence of subcrustal continental earthquakes beneath the Alpine–Himalayan Belt was recognised more than 60 years ago. There is general agreement that most of those beneath the western part of
Formation of arcuate orogenic belts in the western Mediterranean region
The Alpine orogen in the western Mediterranean region, consisting of the Rif-Betic belt and the Apennine-Calabrian-Maghrebide belt, is a classic example of an arcuate orogen. It contains fragments of

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
Extensional collapse of thickened continental lithosphere: A working hypothesis for the Alboran Sea and Gibraltar arc
Several features of the Alboran Sea suggest that it may have been a high collisional ridge in Paleogene time that subsequently underwent extensional-collapse, driving radial thrusting around the
Extension versus compression during the Miocene tectonic evolution of the Betic chain. Late folding of normal fault systems
The westernmost part of the Mediterranean Alpine Belt is represented by the Betic-Rif orogenic belt, around the Gibraltar Arc, which in turn surrounds the Alboran Basin. In the Betic Chain, early and
Tectonic evolution of the Alboran Sea basin
Abstract The Alboran Sea is an extensional basin of Neogene age that is surrounded by highly arcuate thrust belts. Multichannel seismic (MCS) reflection profile data suggest the basin has a complex
Late orogenic extension of the Betic Cordillera and the Alboran Domain: A lithospheric view
The Betic Cordillera of southern Spain provides a clear example of a collisional orogen that has undergone large-scale extensional collapse while convergent motion of the bounding plates continued.
Paleomagnetic rotations and the kinematics of the Gibraltar arc
Paleomagnetic investigations of a Mesozoic limestone sequence around the Gibraltar arc show that there have been large systematic rotations about a vertical axis and imply that there must have been a
The Azores-Gibraltar Plate Boundary: Focal mechanisms, depths of earthquakes, and their tectonic implications
We have analyzed the focal mechanisms and depths of 10 moderately sized earthquakes along the Azores-Gibraltar plate boundary by a variety of methods including formal inversion of the waveform and
