Sedimentologic and petrographic informations on the sampled pebbles. a Stratigraphic and geographic repartition of the Cenozoic succession in the Barrême Basin. The pebbles were sampled in the St-Lions Conglomerates that were deposited at about 30 Ma in the northern part of the Barrême Basin. b Photograph of the St-Lions Conglomerates outcrop. c Detail of the matrix-supported polygenic conglomerates. d Lithological composition of the St-Lions Conglomerates. e Photographs of some lithologies that constituted the pebbles crosscut by quartz–calcite veins and the sampled calcitic cementation that locally replaced the andesitic matrix. Note the size and shape variability of the veins
