Fig. 24

Transect across the Jura platform from the internal to external part following a SW to NE axis along the Jura High chain. Key-events, beds, and surfaces used for correlations between sections are marked by the coloured lines, and the rare ammonite findings are reported on the right side of the logs. Major discontinuities are indicated by thicker lines. This figure highlights the Fort-de l’Écluse carbonate platform (in light blue) followed by the prograding Vallorbe carbonate platform (in purplish), and the Serrières Bed in lowstand prograding wedge (in dark blue). Both urgonian-facies are separated by the flooding series of the Rivière (in turquoise) and Bôle (in dark green) members, and grade north-eastward to the slope deposits of the Gorges de l’Orbe facies
