摘要：
The pelagic limestones exposed in the valley of the Cismon river (near Feltre) appear to represent continuous deposition from Valanginian to Campanian, apart from a short hiatus in the Early Albian. Detrital magnetite is the carrier of remanence in these predominantly white-grey limestones, and a well-defined magnetic stratigraphy has been obtained. The Cretaceous quiet zone at Cismon is totally normal in polarity and stretches from Early Aptian to Early Campanian. Below the Lower Aptian, the Early Cretaceous mixed polarity interval is tentatively correlated with the sequence of geomagnetic reversals derived from the oceanic magnetic anomalies. © 1979.
