Abstract

This study proposes a tectonic reinterpretation of the southwest end of the Cazorla Arc from two different points of view never used before in external zones of the Betic Cordillera: the paleogeographic study of the Triassic sedimentary sequences together with the structural analysis of the ductile fabrics developed in clay- and gypsum-bearing Triassic rocks. This new approach has allowed to distinguish two kinematically distinct tectonic episodes separated in the time: a first strike-slip E-W system of faults followed by a relatively recent strike-slip SE-NW system, both dextral. The study from these points of view of other similar regions could clarify the origin of the so-called Triassic chaotic complexes, at the same time that improve the knowledge of the tectonic evolution of the Cordille.
