Stress analysis based upon the fault sets associated with 300-290 M.a. (Wlodes and greisens) and 274±6M.a. (episyenites) events, have been carried out. The first peak is related to a transtensional strike-slip tectonic regime, with S E-NW compression. The second is a ssociated to an extensional regime, with NE-SW and E-Wextension}, publisher = {Sociedad Geológica de España}, keywords = {Spanish Central System}, keywords = {Fault Analysis}, keywords = {Permian and Upper Carboniferous Tectonic Regime}, title = {Análisis de la fracturación asociada a las alteraciones hidrotermales de tipo Greisen y Episienita en la Sierra del Guadarrama}, author = {González Casado, J.
