A revised Palaeogene lithostratigraphic framework for the Northern Swiss Jura and the Southern Upper Rhine Graben and its relationship to the North Alpine Foreland Basin. Riv. Italiana Pal. Strat. 124/1, 163–246
p.203: The Pulversheim Fm consists mainly of grey to blue massive marls, marls laminated with thin layers of silt or fine sand and marls with intercalated centimetric micaceous fine sand layers and lentils. Fine sands and silts feature planar or rippled bedding (Fig. 25). Massive or rippled fine to medium sand bancs containing plant debris or basal mud intraclasts are occasionally intercalated (Fig. 26). At the base of the Pulversheim Fm millimetric layers of the underlying Hochberg Fm facies may be present. Macrofossils are rare.
