%X The Torcal de Antequera is situated in the Penibetic (part of the Betic External Zone) very near of the contact with the Internal Zone. It has an E-W fusiform shape and corresponds to a monocline structure, surrounded and uplifted by large scale dextral strike-slip faults. Its interior includes a large number of map-scale fractures, most of which can be explained by a mega dextral shear system. The minor structures measured, linked to the faults, are also consistent with this shear system and with its progressive evolution. The deduced predominant direction of s1 is NW-SE, congruent with the oblique displacements occurred between the Internal Zone and the Penibetic in this area; the Torcal area is one of the megastructures formed by it. El Torcal de Antequera est¨¢ situado en el Penib¨¦tico (parte de la Zona Externa B¨¦tica) cercano a la Zona Interna. Tiene una forma ahusada en la direcci¨®n E-O y corresponde a una estructura monoclinal, rodeada y levantada por grandes fallas de desgarre dextrorsas. En su interior existen innumerables fallas, la mayor¨ªa de las cuales pueden explicarse dentro de un sistema de desgarre dextrorso a gran escala. Las estructuras menores medidas, ligadas a las fallas, son consistentes con este sistema de cizalla y con su progresiva evoluci¨®n. La direcci¨®n predominante de s1 deducida es NO-SE. En esta ¨¢rea, el sistema de cizalla est¨¢ ligado a los desplazamientos de la Zona Interna en relaci¨®n con el Penib¨¦tico; el ¨¢rea del Torcal corresponde a una de las megaestructuras formadas en ¨¦l.
