- W2026725859 abstract "Zircons from a metagranite sample from the Lower Gneiss Unit in Limousin (French Massif Central) were dated by the U–Pb ion probe method. Apart from inherited Palaeoproterozoic ages (1.8 to 2.1 Ga), all analyses are concordant to sub-concordant and fall into three age groups: 617 ± 17, 526 ± 14, and 457 ± 23 Ma. Distinct oscillating banding domains within the zircons analysed suggest that the ages correspond to at least two consecutive episodes of protolith reworking. The ages obtained are similar to other found in the French Massif Central, but the fact that here they are seen in a single zircon grain or in a single grain population points out to the cyclic evolution of the protolith in a succession of tectonic events also affecting the microplates between Laurussia and Gondwana. Les zircons extraits d’un métagranite de l’unité inférieure des gneiss dans le Limousin (Massif central) ont été datés par la méthode U–Pb à la sonde ionique. Mis à part les âges paléoprotérozoïques (de 1,8 à 2,1 Ga), toutes les analyses sont concordantes ou subconcordantes, et forment trois groupes d’âges : 617 ± 17, 526 ± 14, et 457 ± 23 Ma. Des zones de croissance oscillatoires observées dans les zircons datés suggèrent que ces âges correspondent à au moins deux épisodes consécutifs de recyclage du protolithe. Des âges similaires ont été obtenus ailleurs dans le Massif central, mais le fait qu’ils soient observés ici dans une seule population de grains révèle le caractère cyclique de l’évolution du protolithe, dans le cadre d’une suite d’événements tectoniques qui affectent les microplaques entre l’Eurasie et le Gondwana." @default.
