Comment on 'Preorogenic exhumation of the North Pyrenean Agly massif (Eastern Pyrenees-France)' by A. Vauchez et al.

摘要

[1] Vauchez et al. [2013] propose a "conceptual model" for the uplift of the North Pyrenean Agly massif related to an Albian northward decollement of the post-Variscan cover of this massif. Understanding and dating the Cretaceous evolution of the Pyrenees are particularly important because this evolution was related to the opening of the Northern Atlantic and to the counterclockwise rotation of Iberia with respect to Eurasia. The Vauchez et al. data concerning the top-to-the-north shearing of the base of the northeastern part of the Agly cover are convincing and confirm one of the conclusions of Paquet and Mansy [1991]. However, several points used for the model, especially chronological aspects, are not well established or contradictory with previous publications.
