Major lithologic features of the Allinges Mb. (a, b) and of the Vouan Conglomerate (c–h). a Massive sandstone accumulation at the large quarry of Allinges. b Erosive microconglomerate overlying a laminated coarse sandstone at the Rocher d’escalade exposure. c The Grande Gueule millstone quarry exposure. Letters refer to close-up views depicted in next sub-figures. d Remnants of millstone extraction from the Grande Gueule quarry. Note the homogeneous lithology of the excavated section. e The Grotte aux Loups exposure (46.3172° N, 6.4445° E) at the Maladière is the easternmost outcrop of the Vouan Conglomerate. f Pinch out and variable pebble size and distribution at the Grande Gueule quarry. Note the large block floating into the sandy matrix and the fining-up grain-size (black triangle). g Clast of black conglomerate of Paleozoic age characterising the Vouan Conglomerate from the Grande Gueule exposure. White circle: lens cap (72 mm). h Marly interval (sequence 3) of the Ruisseau de Curseille (46.2° N, 6.3712° E)
