Stop 3.3 - Kemplich (old gypsum quarry): Middle Keuper (‘Marnes irisées
supérieures’ Fm, with Eo-Cimmerian unconformity)
In this stop (see p. 7 for location), the Eo-Cimmerian unconformity eroded a gypsum bed that could be
equivalent to the Heldburg Gypse (Fig. 33).
Between the SE part of the basin to the NE the ‘Argiles de Chanvilles’ Fm is more and more
developed (Fig. III.2), but less developed than in the centre part of the Paris Basin, where thicker anhydrite
formation occur.
