The cover décollement and the cataclastic Triassic breccias in the Saraillé area: some field aspects. A. 20–30 m thick strongly sheared pink chlorite-talcschists at site of sample SAR30. B. Well-bedded Upper Triassic carbonates entirely changed into a 3–5 m thick magnesitite level (site of sample SAR22). C. Polymictic Triassic tectonic breccias (site of samples SAR17a and SAR17b). D. Brecciated meta-ophite (site of sample SAR14). E. Polymictic Triassic tectonic breccia including clasts of meta-ophite (green), Paleozoic schist (black) and cellular dolostone (“cargneules”) (site of sample BCOR250c).
