p.8: Syn-rift sediments Sedimentary breccias with a variable amount of matrix and intercalated hemipelagic background sediments, sandy limestones and shales conformably overlie the top of the Agnelli Formation or unconformably overlie the older sediments or metamorphic basement rocks (Finger 1978). The very local distribution and the strong variability in composition and texture, typical for syn-rift sediments, have led to different local names for these sediments, such as Saluver Formation (Finger 1978), Bardella Formation (Finger 1978), Salteras Series (Stöcklin 1949) and Salamun Breccia (Stöcklin 1949). In this study, the name "Saluver Group" (Furrer et al. 1985) is used for these sedimentary breccias and sandstones which are often particularly rich in crystalline basement clasts. Characteristic for the sedimentary breccias of the Saluver Group are a general up-section change from pure carbonate to carbonate/crystalline breccias (Stöcklin 1949) and the occurrence of one or more thinning- and fining-upward cycles (Finger 1978). The age of most of the breccias in the Lower Austroalpine units is badly constrained but the observation that these breccias stratigraphically overlie a hardground of Early Pliensbachien age (pers. com. Heinz Furrer) and are themselves overlain by radiolarian cherts of the upper Middle to Upper Jurassic Radiolarite Formation (Baumgartner 1987) makes a Middle Jurassic age for them most likely. The fact that in some places younger strata, sometimes even Lower Cretaceous Argille a Palombini, onlap the breccias and appear to interfinger with them (e.g. Fuorcla Mulix. see below) suggests that some of the breccias might also be younger.
