In Apulia (southern Italy), 11 quarries in late Pliocene and early Pleistocene clays were sampled to study the rotation of the underlying Apulian Unit. To analyze the Natural Remanent Magnetization (NRM) of the samples thermal magnetization was performed. Several NRM-components were distinguished. The component removed between 350--380¿C and 450--480¿C is the most consistent one; it also shows a positive reversal test. There is no rotation for this so-called HT-component. Mean inclination is the same as the inclination of the geocentric axial dipole (GAD) field for the present latitude of the area. It is concluded that these young clays reflect the geomagnetic field quite clear and that this part of the Adriatic microplate did not have any tectonic rotations since the Pleistocene. ¿American Geophsysical Union 1992
