In this study, petro-geochemical, isotopic and geochronological data have been acquired in order to characterize and date fluid circulations within the South Armorican Shear Zone. These circulations have been dated by U-Pb on both zircon and monazite and by muscovite 40Ar/39Ar analyses, extracted from mylonites and syntectonic granites displaying evidence of hydrothermal alteration. At 315 Ma, the South Armorican Shear Zone localized the circulation of magmato-metamorphic fluids, responsible for the crystallization of giant quartz veins parallel to its main strike. Around 300 Ma, an influx of meteoric fluids is recorded in mylonites, as well as in some granitic samples and in quartz veins oblique to the South Armorican Shear Zone, interpret...
