RT Journal Article T1 Actividad paleo-hidrotermal episódica en la Sierra deGuadarrama (Sistema Central Español): nuevas edades K-Ar ycorrelación tectónica con la Cordillera Ibérica A1 Galindo Francisco, María Del Carmen A1 Casquet Martín, César A1 Tornos Arroyo, Fernando AB Episodic hydrothermal alterations in the Sierra de Guadarrama took place between ca. 300 Ma and10 Ma. New K-Ar ages for hydrothermal minerals have been obtained that along with previous data allowto better constrain the late- to post-Variscan history of tectono-hydrothermal activity. This activity canfurther be correlated with Alpine tectonic events in central Iberia recorded in Permian to Cainozoicsedimentary basins. Dating of hydrothermal events in the basement is thus a useful tool to better constrainthe chronology of tectono-sedimentary events in the cover.
