Abstract

A structural and mineralogical study of a group of arsenopyrite-bearing hydrothermal dikes located in the central area of the Sierra de Gredos has been carried out. These mineralizations indicate a dominance of the high-temperature associations (arsenopyrite, pyrite and pyrrhotite) over the lower temperature ones. Four deformational stages evolving from mainly ductile to brittle regimes have been identified. A single phase of progressive deformation generated structures progressively smaller in size, with an E-W-oriented/horizontal maximum finite shortening axis. This study emphasizes the relationships between deformative processes and mineralization evolution in the sense that this evolution appears to be strongly inf!uenced by the size and character of the tectonic structures.
