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-WextensionspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Spanish Central SystemFault AnalysisPermian and Upper Carboniferous Tectonic Regimejournal articleopen access
