英文摘要	In the Variscan French Massif Central and Armorican Massif, the tectonic significance of a widespread NW-SE-trending stretching lineation, coeval with medium pressure-medium temperature metamorphism, is an open question. Based on a structural analysis in the southern part of the Massif Central, we show that this top-to-the-NW shearing is a deformation event, referred to as D2, which followed a D1 top-to-the-south shearing Devonian phase, and was itself re-deformed by a Late D3 Visean-Serpukhovian southward-thrusting event. We date the D2 phase at 360 Ma (Famennian-Tournaisian boundary). In the Armorican Massif, D2 is the "Bretonian phase'' recorded in the metamorphic series and sedimentary basins. Geodynamically, D2 is related to a general northwestward shearing during the Laurussia-Gondwana collision, which occurred after the closure of the Rheic Ocean, as indicated by the emplacement of the Lizard ophiolitic nappe in Britain. The leftlateral Nort-sur-Erdre fault accommodated the absence of ductile shearing in Central Armorica. (C) 2017 Academie des sciences. Published by Elsevier Masson SAS. All rights reserved.
