p.105: Within the Kaufmanni Limestone of the Lower Sibetsegg profile (GR 733.7/197.7) (Wegmann 1961), there is a local concentration of alveolinids overlain by a sterile marl; this foraminifera is usually found in protected lagoonal environments (Ghose 1977; Racey 1988). The Alveolina Limestone represents a lateral facies change within the Kaufmanni Limestone, and may correlate with the uppermost glauconitic limestone within the Merenegg profile (Fig. 4) which also contains alveolinids and the encrusting foraminifera Planorbulina sp.. The overlying marl at Lower Sibetsegg may correlate with the Globigerina-xich horizon within the Chalberboden profile (Fig. 4), which also contains (reworked) alveolinids.
