Reinterpretation of palaeomagnetism of the Colli Euganei and Monti Lessini (Italy)

Main Article Content

H. Soffel


New information on the age of the volcanics from the Colli Euganei and Monti Lessini (Northern Italy) collected by Channell et al. (1978) show that the divisions made by Soffel (1972, 1974, 1975a) of palaeomagnetic directions from the two areas into Eocene and Oligocene groups had to be modified. From the data of both sampling areas alone an anticlockwise rotation of the area between Eocene and Oligocene can no longer be clearly demonstrated. However, a combination of the predominantly Oligocene data from the Colli Euganei with the predominently Eocene data from the Monti Lessini as well as their comparison with corresponding palaeomagnetic data from Stable Europe brings enough statistical evidence for an anticlockwise rotation of the area of at least 20-30° between Upper Eocene and Lower to Middle Oligocene.
