Dr Miguel Calvo, in his new book (2018) "Minerales y Minas de España, Volumen IX, Silicatos", indicates epidote coating quartz crystals at this locality. No analysis is presented, so it could I suppose be clinozoisite too.
There seems to be a lot of micro hematite too, coating quartz and embedded in the youngest layer of feldspars, so probably an Fe-rich environment in the final stages.
