182 GNGTS 2018 S essione 1.2 of folding and thus of strike-slip faulting. Publicly available high-resolution digital elevation models, 0.5 mt/px orthophotos, and 1:50.000 geological map have been combined to carry out a remote sensing analysis of the possible neotectonic features, which has been integrated with the study of long profiles of the streams crossing the folded structure and displaying fluvial captures. Our study provide evidence of fluvial meander and alluvial fan tilting during the late Miocene or earlier. Instead, the fluvial captures developed after the end of folding, in the framework of the regional capture of the tributaries of the Duero river by the Ebro River since the late Pliocene period. In agreement, we conclude that the Rojas fold system has started its last stage of folding at least during the Late Miocene but it is essentially inactive at least since the late Pliocene.

The Tyrrhenian coast of Calabria-Lucania boundary has been investigated in depth combining geomorphological and stratigraphical approaches to get new quantitative data on its surface uplift history. In the study region, which spans from Maratea (Basilicata region) to Scalea (Calabria region), starting from Late Tortonian times back arc extension and opening of the Tyrrhenian Sea was coeval with the shortening in the chain (e.g., Butler et al. , 2004, and references therein). Surface uplift is referred to as “the displacement of the Earth’s surface with respect the geoid” (England and Molnar, 1990) or, analogously, with respect to the mean sea level. Erosional indicators of fossil sea-level positions, e.g. abrasion platforms, marine notches and potholes, are well recorded on hard rocks (Evelpidou and Pirazzoli, 2015), as are those forming
