Arroyo de la Yedra, Manzanares el Real, Madrid, España
The episyenites from the Sierra de Guadarrama (Spanish Central System) were formed by the hydrothermal alteration (dequartzification and alkalinization) of granitoids. The alteration took place on a regional scale, in the Lower Permian (277 Ma), in a brief period of time. Structurally, these rocks define a regional extensional geodynamic frame, with a NNE-SSW main regional extension direction (Caballero et al., 1996).
The amphiboles at the locality show a large compositional variation, ranging from arfvedsonite/magnesio-arfvedsonite/riebeckite to more Li-rich phases such as leakeite, pedrizite root name minerals and clino-holmquistite. The amphiboles show large local variation and can only be differentiated by analytical methods capable of identifying the Li content (Caballero et al., 2002).
