International audienceGiant quartz veins associated with the South Armorican Shear Zone (SASZ) record huge fluid circulation during the Hercynian period. A regional-scale mapping of veins allows identifying two groups of veins on the basis of their geometric relationship with the SASZ (fig. 1). Veins from the fist group are parallel to the SASZ and associated with zones of intense deformation, veins from the second group developed on the southern edge of the SASZ, in an oblique meridian direction. The former likely record infiltration of fluids along permeable pathways; the latter may represent crustal-scale tension gashes associated with East-West ó3 direction in the regional context (North-South shortening and dextral working of the SASZ ...
