Abstract

A palaeomagnetic investigation of the uppermost 12 meters of the Miocene Gram Formation revealed the occurrence of four normal and three reverse polarity zones two of which are probably indications of short excursions of the geomagnetic field. The calculated palaeopole position deduced from the normal polarity zones is 84 N, 189 E. The variations in magnetic susceptibility and intensity may be related to grain size variations of the magnetic grains. A correlation with polarity Chron C5 (10 m.y.) is suggested, based on published biostratigraphy data.
