Two main tectonothermal events are recorded: D1 is compressional and related to the variscan collision that produces northeast-eastward thrusting and associated folding; D2 has an extension nal character and produces, as the main feature, the development of a kilometric-scale ductile shear zone and a series of associated low grade detachments where D1 structures are overprinted and trasposed at all scales. The final structural pattern is completed by a set of late westward facing minor D3 structures that did not significantly modified the previous geometry.spaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Extensional tectonicsShear ZoneCentral-lberian ZoneSpain Central SystemSomosierrajournal articleopen access
