Journal Article
Published: 01 November 2012
Journal of the Geological Society (2012) 169 (6): 667–679.
...Ana Crespo-Blanc; J. C. Balanyá; I. Expósito; M. Luján; E. Suades Abstract The external wedge of the Gibraltar Arc orogenic system (western Mediterranean) is a natural case of a fold-and-thrust salient. Although at the scale of the arc a swing of the structural trend can be observed, the presence...

...Ana Crespo-Blanc; Dominique Frizon de Lamotte Abstract The Betics and Rif cordillera constitute the northern and southern segments of the Gibraltar arc. Two different fold-and-thrust belts, deriving from the South Iberian and Maghrebian paleomargins respectively, developed in front of this orogenic...

Journal of the Geological Society (1998) 155 (1): 193–207.
...ANDREW I. KIRKER; JOHN P. PLATT Abstract We have investigated the kinematics of deformation in a sector of the Gibraltar arc in SW Spain, by synthesizing lineation data from major faults, the variation in structural trends, and palaeomagnetically determined vertical-axis rotations. The kinematic...

Geology (1992) 20 (4): 311–314.
...E. S. Platzman Abstract 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 significant component of westward motion within the Betic-Rif orogenic belt...

...J. P. Platt; R.L.M. Vissers Abstract 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 Gibraltar arc. (1) The basin is underlain by thin (13-20 km...

Tectonic map of the Gibraltar arc formed by the Betics, Rif, and the Alboran Sea Basin and the continuation of this orogenic system into the Gulf of Cadiz. Map updated from Soto et al. (2010), including various sources for the Alboran Sea (Comas et al., 1992, 1999; Chalouan et al., 1997; Ballesteros et al., 2008; Martínez-García et al., 2011, 2013), the Gharb Basin (GB) and the offshore area in Morocco (e.g., Flinch, 1996; Zizi, 2002), the Tell region and the Algerian Basin (AB; e.g., Medaouri et al., 2012), and the Gulf of Cadiz (e.g., Gràcia et al., 2003; Medialdea et al., 2009; Zitellini et al., 2009). The Subbetic and the Maghrebian paleomargins (or covers) are undifferentiated in the map (white areas in the onshore areas). Mud volcanoes, shale diapirs, and salt culminations in the Gulf of Cadiz and in the Alboran Sea are compiled from numerous sources (e.g., Comas et al., 2003; Pinheiro et al., 2003; Somoza et al., 2003; Medialdea et al., 2009; Blinova et al., 2011; Somoza et al., 2012; Soto et al., 2012; Gennari et al., 2013; Hensen et al., 2015). Numbered wells correspond to Alboran A-1 (w1), Andalucia A-1 (w2), El-Jebha (w3), Ocean Drilling Program (ODP) Site 976 (w4), ODP Site 977 (w5), ODP Site 978 (w6), ODP Site 979 (w7), and Deep Sea Drilling Project (DSDP) Site 121 (w8). The studied Andalucia G-1 well is indicated by G1. A rectangle marks the region in the vicinities of the studied well, where a detailed study of the mobile shale structures has been conducted. AI = Alboran Island; EAB = East Alboran Basin; SAB = South Alboran Basin; WAB = West Alboran Basin.

Schematic crustal section across Gibraltar Arc–southwest Iberia margin (SIM) region. Approximate direction and position of segment A–B are shown in Figure 1C. Three representative seismic sections (clockwise: BS22, SIS22, and IAM4) are also depicted. Refer to Figure 1C for vertical and horizontal scales. Note that it is not clear if Gorringe roots in intralithospheric décollement, or if it cuts through lithosphere.
