Figure 46: Sedimentary log of Bitche (Stop 4.3) by Bock et al. (2001) which differs from our observations. VG1 and VG2 are paleosol key-beds defined by Müller (1954) 72 Hardegsen unconfromity (From this study)
Stop 4.4 - Bitche (Citadel): Middle Buntsandstein (Karlstal facies of the ‘Grès vosgien’ Fm) In this outcrop (Fig. 44), the Karlstal facies of the ‘Grès vosgien’ Formation are well exposed (Fig. 47). These facies are characterized by fluvial and aeolian deposits. Figure 47: Outcrops of Bitche Cidatel. Facies association: Fluvio-aeolian overbank environments This facies association is observed in the upper ‘Grès vosgiens’ Formation, so-called the Karlstal Formation (Fig. II.3, II.4). This association is very sandy and characterized by vertical pattern, from the base to top (defined on the cores of the Soultz-sous-Forêts well): - planar laminated sands containing cm-thick coarse sand layers, - cm-thick planar laminations of fine to medium sand, that sometimes grade upward into oscillatory ripples - laminated silstones, or fine sandstones, along with red mudstones, sometimes bioturbated. These facies can be more or less bioturbated. They form fining-upward sequences ranging in thickness from dm up to 5 m, with frequent mud-crack structures at their top. Locally, aeolian facies can be interbedded within these deposits. The first facies, interpreted as fluvial sheet flood deposit evolves vertically into wave-ripple facies that suggest flood currents entering a subaqueous environment, a hypothesis 73
