Abstract

Thc AMS fabric of an uppcr Miocene marly scqucnce exposcd along the Morra creek (Tuscany. Italy) changes from inverse to normal from thc bouom to the top of thc section. The change is graduai. with the occurrence of anomalous magnetic susceptibility fabric at some le,·cls. The anhystcrctic remanence fabric is alwavs norm l throughout the sequence. Thc changcs in the AMS fabric seem to be controlled by sedimentological variations, with the inverse susceptibiliry fabric related to the abundance of iron-bearing carbonates in the lower part of the section In the upper part of the section subtle changes in the detrital inputs in the basin and particularly a larger contribution of clayey and ferromagnetic particles, turned the MIS fabric to a normal type
