L'ANISOTROPIA DELLA SUSCETTIVITA' MAGNETICA NELLA RISOLUZIONE DI PROBLEMI GEODINAMICI: ALCUNI ESEMPI NELL'APPENNINO CENTRO-MERIDIONALE

Abstract

Anisotropy of Magnetic Susceptibility (AMS) studies constitute an effective tool of structural analysis for almost ali rock types. We investigated the AMS of sedimentary units, upper Cretaceous to lower Pleistocene in age, from differ­ent structures in central-southern Apennines. The obtained results show magnetic fabrics which are typical of undeformed or weakly deformed sediments. Such fabrics are strictly relat­ed to the structural setting and allow both the reconstruction of the bedding attitude in massive clayey units and the deter­mination of the orientation and the relative degree of defor­mation in each lithostratigraphic unit.
