Summary:The U-Pb isotopic composition of monazite and zircon from the W part of the Saint-Sylvestre massif (French Massif Central, Hercynian Chain) give an upper intercept at 324 + or - 4 m.y. The Hercynian post-metamorphic peraluminous magmatism (Limousin type) in the French Massif Central is clearly Carboniferous. The monazite U/Pb system is locally reset by the thermal influence of late-Carboniferous quartz-dioritic and lamprophyric magmatism. [M.L.]
