Abstract
La fosa de Garganta del Villar (Sistema Central español) es una depresión tectónica subromboidal sobre zócalo cristalino, que localmente contiene depósitos cenozoicos (Paleógeno-Cuaternario). La interpretación geomorfológica, sedimentológica y de la mineralogía de arcillas, permite aportar nuevos datos sobre la evolución geodinámica durante el Cenozoico de este área del Macizo HercÍnico. Las etapas que configuran dicha evolución son correlacionables, en gran medida, con aquéllas establecidas por otros autores en la zona de contacto entre las grandes cuencas sedimentarias (Duero y Tajo) y el Sistema Central. Sin embargo, un buen registro de morfologías y depósitos cuaternarios de la fosa, han hecho posible matizar y complementar la sucesión de eventos pleistocenos de la misma, que evolucionó con cierta independencia respecto al resto del macizo montañoso.
The Garganta del Villar Depression (Spanish Central System) is a tectonic basin that contains Cenozoic sediments (Paleogene and Quaternary). Geomorphological, sedimentological and mineralogical interpretations of the basin configuration and its deposits, permits us to arrive new data about geodinamic evolution of this area of Iberian Variscian Massif during Cenozoic times. The different stages are correlatable to those established by other works, that center their analysis in the limits with the two large sedimentary basins, Duero and Tajo. Nevertheless, the excelent Quaternary record let us to complete the succession of Pleistocene events in this zone, that manoeuvred with a evident independency of the rest of the mountainous system.
