SISTEMA DE PLIEGUES ACTIVOS EN EL MARGEN CONTINENTAL SEPTENTRIONAL DEL MAR DE ALBORÁN (MEDITERRANEO OCCIDENTAL)

Abstract

En el margen septentrional del Mar de Alborán, la deformación compresiva relacionada con la convergencia entre las placas de Eurasia y Nubia se resuelve mediante una intensa fracturación según dos grandes sistemas de fallas de dirección NNE-SSO con movimiento sinestro y NO-SE de desplazamiento dextral-normal. El análisis estructural de los elementos geomorfológicos presentes en el fondo marino permite establecer, además, una serie de elementos morfológicos generados por la actividad de pliegues anticlinales y sinclinales que conforman una serie de elevaciones de dirección N050-060ºE. Estos pliegues deforman a las unidades sedimentarias superficiales y han sido activos al menos durante el Cuaternario, como lo demuestra el patrón de espesores de las unidades sísmicas afectadas por el plegamiento y la deformación de la superficie erosiva asociada a una terraza contornítica. Este patrón de estructuras se interpreta como generado por la deformación existente sobre una falla de cabalgamiento, vergente hacia el norte, que asume parte de la deformación compresiva causada por la indentación del bloque de la Dorsal de Alborán. In the northern margin of the Alboran Sea, the compressive deformation related to the convergence between the Nubian and Eurasian plates is resolved by an intense fracturing along two large fault systems trending NNE-SSW with left-lateral movements and NW-SE with right-lateral normal components. The structural analysis of the geomorphological elements on the seafloor also allows us to establish a series of morphological elements generated by the activity of some anticline and syncline fold sets. It is basically a series of ridges heading N050-060ºE. These folds deform the shallow sedimentary units and have been active at least during the Quaternary, as evidenced by the thickness pattern of seismic units affected by the folding and the deformation of an erosive surface associated with a contouritic terrace. This pattern of structures is interpreted to be generated by the overlying deformation on a thrust fault, verging towards the north, which assumes part of the compressive deformation caused by the indentation of the Alborán Ridge block.
