Geological map of the northeastern sector of the high Agri Valley, Southern Apennines (Basilicata, Italy)

The high Agri Valley represents a regionally important Pleistocene tectonic basin superimposed on the fold-and-thrust belt of the Southern Apennine, which has developed since the Late Oligocene – Early Miocene. Impressive morpho-structural features related to post-orogenic faulting can be identified along the northeastern margin of the basin, in the Marsicovetere area, where the main tectonic units involved in the southern chain are exposed. In this work, we present a geological map at 1:25,000 scale and cross sections of the Marsicovetere area. The geological map documents the effects of the different tectonic stages in the polyphase evolution of the Southern Apennines, which are shown in several outcrops of the high Agri Valley. More specifically, the study area shows that the early contractional structures have been dissected by several sets of faults with strike-slip and extensional kinematics. Based on geological mapping and structural analysis we distinguished three different homogeneous fault popul..
