Stop 2.3 - Suriauville (road cutting): Lower Keuper (‘Dolomie de Vittel’ Fm= ‘Dolomie
inférieure’ of the Lettenkohle)
Figure 18: Location of the outcrop of Suriauville and Crainvilliers
This outcrop (Fig. 18) is attributed to the restricted marine environment of the ‘Dolomie inférieure’ of
the Lettenkhole. In this area (south of Vittel), its lower boundary becomes difficult to place owing to a
progressive dolomitization affecting finally, to the south (towards Burgundy) the whole 'Muschelkalk
supérieur' (Fig. 19).
