The 39Ar/40Ar dating of illite, probably related with the hydrothermal activity responsible of the second type of mineralizations, yields 361 ± 2 Ma. This age is some 25-50 Ma older than the age of granitic intrusions in the area, and could be the age of the epigenetic mercury mineralizationsspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/GeochronologyMineral depositsMercuryHercynian39Ar/40Arjournal articleopen access
