Significado geodinàmico de las vergencias al norte en el NE de la Provincia de Sevilla (Zona de Ossa-Morena)

Abstract

The area s tu d ie d is characterized by the occurrence o f structures w h ich associate a N te c to n ic vergence. These are the results of deformational features varying from localized mylonite generation in highly strained granitic parent rocks to rough-cleavage development in the less deformed ones of the metasedimentary succession. In the context of the Ossa-Morena Zone, where most often structures associate a dominant S vergence, the structures described here would reflect, in turn, the existence of upper Paleozoic shear zones whose orientation is antithetic with respect to that of Hercynian subduction and obduction of the South-Portuguese Zone below the Ossa-Morena
