Actividad paleo-hidrotermal episódica en la Sierra de Guadarrama (Sistema Central Español): nuevas edades K-Ar y correlación tectónica con la Cordillera Ibérica

Episodic hydrothermal alterations in the Sierra de Guadarrama took place between ca. 300 Ma and 10 Ma. New K-Ar ages for hydrothermal minerals have been obtained that along with previous data allow to better constrain the late- to post-Variscan history of tectono-hydrothermal activity. This activity...

Sumario:Episodic hydrothermal alterations in the Sierra de Guadarrama took place between ca. 300 Ma and 10 Ma. New K-Ar ages for hydrothermal minerals have been obtained that along with previous data allow to better constrain the late- to post-Variscan history of tectono-hydrothermal activity. This activity can further be correlated with Alpine tectonic events in central Iberia recorded in Permian to Cainozoic sedimentary basins. Dating of hydrothermal events in the basement is thus a useful tool to better constrain the chronology of tectono-sedimentary events in the cover.
