Structure and evolution of the “Olistostrome” complex of the Gibraltar Arc in the Gulf of Cádiz (eastern Central Atlantic): evidence from two long seismic cross-sections

TL;DR: In this article, the authors address the questions of what caused Oligocene rollback initiation, and how its subsequent evolution split up an originally coherent fore arc into circum-southwest Mediterranean segments.

TL;DR: In this article, an initial SE-dipping slow subduction of the Ligurian-Tethys realm beneath the Malaguide upper plate unit is proposed as an efficient geodynamic mechanism to structure the arcuate Betic-Rif orogenic system.

TL;DR: In this paper, a synthesis of work conducted on the continental margin of the Gulf of Cadiz using a broad database collected by several cruises and projects supported by the Spanish Research Council and the NRL and Naval Oceanographic Office (USA), including: bathymetry, sidescan sonar imagery, seismic profiles, sediment cores, submarine photographs and physical oceanographic data, has enabled to establish a detailed understanding of the morphologic development of the margin, its Pliocene and Quaternary stratigraphy, and a full characterization of the contourite depositional system (CDS

TL;DR: In this paper, multichannel seismic reflection images across the transition between the east Alboran and the Algero-Balearic basins show how crustal thickness decreases from about 5 s two-way traveltime (TWTT, ∼15 km thick) in the west to ∼2 s TWTT typical of oceanic crust (∼6 km thick).

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.

TL;DR: In this paper, the authors show that the Mesozoic-Cenozoic stratigraphic succession of western Europe can be subdivided into a series of transgressive-regressive facies cycles (second order, 3-50 m.y.).

TL;DR: In this paper, a revised kinematic model for the motions of Africa and Iberia relative to Europe since the Middle Jurassic is presented in order to provide boundary conditions for Alpine-Mediterranean reconstructions.
