This study aims at investigating the controlling factors of repeated inversion and fault-reactivation phenomena, both positive and negative, within orogenic domains. The study has been carried out in the seismically and tectonically active Agri Valley basin, in the axial zone of the southern Apennines of Italy. Fieldwork was based on the compilation of an original 1:25.000 scale geological map of about 120 Kmq, on the construction of cross sections, and on the kinematic analysis of the major tectonic structures outcropping along the NE edge of the Agri Valley. One key feature outlined by this new survey is the recognition and mapping of the Sorgente dell’Acero Member, a stratigraphic unit that previous workers had only described as part of the Calcari con Selce Formation. Furthermore the present research provides important constraint on the study of active tectonics in the High Agri Valley. In order to characterize the recent faults and develop a correct census of the sismogenic structures it is fundamental to reconstruct a correct sequence of tectonic events that occurred in the area, separating the effects of fossil from those of active structures.
