Researchers agree on the presence throughout this area of a main right-lateral fault zone (e.g., Sanz de Galdeano et al, 1985;Galindo-Zaldívar, 1986;Sanz de Galdeano, 1989;Jabaloy et al, 1992;Galindo-Zaldívar et al, 2003;Martínez-Díaz and Hernández-Enrile, 2004;Martínez-Martínez et al, 2006;Sanz de Galdeano et al, 2010). However, controversy persists concerning the deep continuity of the structures, the relationships of the exposes faults with seismicity, the driving mechanisms, and in some cases the age of fault activity.…”

“…The folds have been interpreted as caused by isostatic rebound in response to extensional denudation along the regional extensional detachments (e.g., Martínez-Martínez et al, 2002;Augier et al, 2005;Meigninger and Vissers, 2006). Alternatively, we consider them as contractional folds developed above upper-crustal detachments developed in a collisional framework (e.g., Weijermars et al, 1985;Montenat and Ott d'Estevou, 1990;Sanz de Galdeano and Vera, 1992;Martínez-Martínez et al, 1995;Galindo-Zaldívar et al, 2003;Sanz de Galdeano and Alfaro, 2004;Pedrera et al, 2009b). In any case, these folds contribute to the uplift of the northern boundary of the Alborán Basin gradually disconnecting the now emerged intramontane basins (Comas et al, 1992(Comas et al, , 1999 and inducing the development of the present-day relief ( Fig.…”

“…It is widely accepted that compressional and extensional structures have deformed the Internal Zones of the Betic Cordillera since the Late Miocene. This region exhibits a variety of deformational styles, dominated by folds, right-lateral and normal faults in the central Betics (e.g., Galindo-Zaldívar et al, 2003), and by large left-lateral strike-slip faults in the eastern sector of the cordillera that also interact with folds and normal/normal-oblique faults (e.g., Martínez-Díaz, 2002;Masana et al, 2004;Booth-Rea et al, 2003;Pedrera et al, 2010a). The present study attempts to sketch a coherent picture of these recent tectonic structures that deform the central-eastern (from the longitude 3.1ºW to 1.7ºW and to the south of 37.525ºN) Internal Zones of the Betic Cordillera (Fig.…”

“…Consequently, intramontane sedimentary basins gradually became isolated from the original Alborán basin, some completely emerging (e.g., Braga et al, 2003). This continent collision is still active at a rate of 4-5 mm/yr (Argus et al, 1989;DeMets et al, 1990DeMets et al, , 1994 and continues driving the development of active folds and faults (e.g., Sanz de Galdeano et al, 1995;Galindo-Zaldívar et al, 2003). Therefore, current displacement of the Earth's surface reveals the oblique convergence between the Iberian and African plates, showing a movement of the Eurasian plate and the Betic Cordillera toward the SSW/SW with respect to the African plate (Stich et al, 2006;Fadil et al, 2006;Tahayt et al, 2008;Vernant et al, 2010), which is roughly in accordance with the present-day stress setting (e.g., Fernández-Ibáñez et al, 2007;Pedrera et al, 2011).…”

The most recent tectonic structures of the central-eastern Internal Zones of the Betic Cordillera (from 3.1ºW to 1.7ºW and to the south of 37.525ºN) include fault and folds developed from the Late Miocene onwards, which are related to N-S/NW-SE directed continental collision and moderate thickening of a crust that is relatively hot at depth. In this setting, E-W to WSW-ENE folds, with locally associated E-W transpressive right-lateral and reverse faults, favoured the emersion of the northern Alborán basin palaeomargin and the progressive intramontane basin disconnection. The NNE-SSW to NE-SW trending regional left-lateral Palomares and Carboneras fault zones are dominant structures in the easternmost part of the cordillera. In addition, NW-SE to WNW-ESE trending normal and oblique-slip normal faults are widespread. The collision is still active and continues to drive active folds and faults, some probably being the likely source of moderate-sized earthquakes. The Campo de Dalías and surrounding sectors, deformed by active ENE-WSW folds and NW-SE to WNW-ESE oblique-slip normal faults, are probably the sites with the largest FRQFHQWUDWLRQ RI VLJQL¿FDQW HDUWKTXDNHV GXULQJ UHFHQW \HDUV 0RGHUDWHPDJQLWXGH HDUWKTXDNHV 0Z WR KDYH RFFXUUHG WKHUH at fairly regular intervals, in 1804, 1910, and 1994. Toward the east, NW-SE trending normal faults extending from Almería to the Tabernas basin deform the Quaternary rocks with associated moderate seismicity (the 2002 Gergal Mw 4.7 earthquake, and possibly the 1894 Nacimiento earthquake, felt with intensity VII). In the Sorbas-Vera basin, the Palomares fault zone is also responsible for moderate-sized earthquakes (1518 Vera earthquake). In the Almanzora corridor, NW-SE to WNW-ESE trending Lúcar-Somontín faults also could be considered one of the possible source of moderate-magnitude seismicity (1932 Lúcar, Mw 4.8 earthquake felt ISSN (print): 1698-6180.

Tectonic inversion of an asymmetric graben: Insights from a combined field and gravity survey in the Sorbas basin

et al. 2014

The formation of sedimentary basins in the Alboran domain is associated with the exhumation of metamorphic core complexes over a circa 15 Ma period through a transition from regional late-orogenic extension to compression. An integrated study coupling field analysis and gravity data acquisition was performed in the Sorbas basin in the southeastern Betic Cordillera. Detailed field observations revealed for the first time that extensional tectonics occurred before shortening in this basin. Two extensional events were recorded with NW-SE to N-S and NE-SW kinematics, respectively; the first of which being likely responsible for the basin initiation. Tectonic inversion of the basin then occurred around 8 Ma in an overall approximately N-S shortening context. Two-dimensional gravity sections reveal that the basin acted as an active depocenter as the basin floor locally exceeding 2 km depth is characterized by a marked asymmetric architecture. Based on this integrated study, we explore a new evolutionary scenario which can be used as a basis for interpretations of the Neogene tectonic history of the southeastern Betics.

Neogene to recent contraction and basin inversion along the Nubia-Iberia boundary in SW Iberia

et al. 2017

The SW of Iberia is currently undergoing compression related to the convergence between Nubia and Iberia. Multiple compressive structures, and their related seismic activity, have been documented along the diffuse Nubia‐Iberia plate boundary, including the Gorringe bank west of the Gulf of Cadiz, and the Betic‐Rif orogen to the east. Despite seismic activity indicating a dominant compressive stress along the Algarve margin in the Gulf of Cadiz, the structures at the origin of this seismicity remain elusive. This paper documents the contractional structures that provide linkage across the Gulf of Cadiz and play a major role in defining the present‐day seismicity and bathymetry of this area. The structures described in this paper caused the Neogene inversion of the Jurassic oblique passive margin that formed between the central Atlantic and the Ligurian Tethys. This example of a partially inverted margin provides insights into the factors that condition the inversion of passive margins.
