Col de Maurin outcrops. a Simplified geological map of the Col de Maurin area (see Additional file 1); b Interpreted panorama, blue line marks the trace of a suspected paleofault interpreted to be located between the steeply SW-dipping and overturned Permian meta-andesite (AMA sub-unit) and younger formations (CCH sub-unit); c Proposed schematic reconstruction of the original tectono-stratigraphic setting by simple rotation of the overturned sequence seen in Fig. 7a including the suspected Late Cretaceous fault, into an upright position; d Triassic dolostone pebbles and clasts the stratigraphic base of the “marbres en plaquettes” (see b for the location of this outcrop), e micrograph showing dolostone clasts embedded in the fine grained calcite and detrital quartz matrix of the Upper Cretaceous–Paleocene “marbres en plaquettes”
