Stop 3.8 - Grosbliederstroff (N61 road cutting): Hardegsen unconformity (between Middle and Upper Buntsandstein) The Hardegsen unconformity (Fig. III.2, III.3, III.4) is well marked in this outcrop (Fig. 37). The ‘Grès vosgien’ Formation is truncated by channel like structures filled with conglomerate facies (Fig. 39). This conglomerate facies is attributed to the ‘Conglomérat de Bitche’, very different of the ‘Conglomérat principal’; it contains ‘Conglomérat principal’ pebbles mixed with pedogenic carbonate and carnelian pebbles reworked from the ‘Zone Limite Violette’. In some places this conglomerate is completely lacking, and the ‘Couches intermédiaires’ Fm rests directly above the ‘Grès vosgien’ separated by the Hardegsen unconformity. The two formations can be easily distinguished by the systematic presence of micas, numerous (and sometimes very coarse) feldspars and subangular quartz grains in the ‘Couches intermédiaires’ Fm.

This is a particular load-cast structure, which occurs on the lower surfaces of beds of sandstones interbedded with mudstone, and forms pseudonodules in the sandstone facies. In some case, there is no sign of an overlying sandstone and the isolated pseudonodules ‘float’ in the mudstones (Collison and Thomson, 1993). 66
