Preliminary results of a study of four successive sedimentary geomagnetic reversal records from the Mediterranean (Upper Thvera, Lower and Upper Sidufjall, and Lower Nunivak)

Abstract

The results of a study of four successive Early Pliocene geomagnetic reversal records are presented. The polarity transitions have been recorded in the Trubi formation of Calabria (S. Italy). The lower Sidufjall and Lower Nunivak records are nearly identical and have a zonal harmonic content similar to records reported for the Matuyama—Brunhes polarity transition.
