Abstract

Eocene "syntectonic" remagnetization has been documented throughout the Corbieres orocline, from the Fenouilledes area to the Saint-Chinian arc. Analysis of the Saint-Paul de Fenouillet synclinorium shows that, although the main part of this area retained its initial E-W orientation, its eastern end was affected by a strong anti-clockwise rotation. The N-S part of the orocline is composed of blocks that are several kilometres in size, which display homogeneous anti-clockwise rotations that differ from one block to another. Paleomagnetism brought out the importance of the Vingrau structure that trends NE-SW like the fault network of the Cevennes, and which itself separates blocks affected by differing amounts of rotation. Moreover, it has been shown that the basement has also been affected by the same rotation as the overlying Corbieres thrust sheet. Comparison between the paleomagnetic data and the remagnetization obtained in the Cevennes area (which dated the MVT ore deposit to the Eocene), shows that similar remagnetization also affects the Pyrenean foreland.
