"To simplify the definition of the [Wallau-Hochberg Fm boundary] we consequently exclude the microfossil content as correlative tool, since it rather represents the expression of quickly shifting palaeoenvironmental conditions (e.g. increasing water depth in the transgressive system tract) in a palaeogeographically complex area. The transition to the overlying Hochberg Fm therefore sees an abrupt change to dark brown to black, finely laminated marls bearing abundant marine macrofossils and intercalations of calcareous nannoplankton mass occurrences (white laminae). Near the basin margins (e.g. southern Sundgau and Laufen subbasin; Förster 1909a; Koch 1923) this lithological change can be somewhat less distinct, but remains recognisable."

p.193: The Wallau Fm consists of bioturbated, generally massive or indistinctly stratified brown, green and grey marls with occasional silt/sand layers and rare macrofossils (Grimm & Radtke 2002; Roussé 2006). Closer to the basin margin the silt/sand content may be higher. The Wallau Fm is recorded from the entire URG and represents the basinal analogue of the coeval coastal Lörrach Fm. It is however absent in the Laufen, the Delémont and probably the Ajoie subbasins, which has already been illustrated schematically by Schneider (1960) and Fischer (1965a).
