A stratigraphic comparison with neighbouring pre-Variscan outcrops from the Montagne Noire (southern French Massif Central) and Sardinia is related to i) the absence of Cadomian deformation close to the Ediacaran-Cambrian boundary interval; ii) the presence of an episodic, Cadomian-related, acidic-dominant volcanism related to carbonate production punctuating the Ediacaran-Cambrian transition, similar to that recorded in the northern Montagne Noire; and iii) the lack of Guzhangian (Cambrian Epoch 3) regressive shoal complexes present in the Montagne Noire and probably in Sardinia.17 p.application/pdfengcc-by-sa (c) Padel, Maxime et al., 2018http://creativecommons.org/licenses/by-sa/3.0/esCambrià (Període)PaleogeografiaPirineusCambrianPaleogeographyPyreneesinfo:eu-repo/semantics/article6836962020-01-23info:eu-repo/semantics/openAccess
