TETTONICA E SEDIMENTAZIONE (LIAS-PLEISTOCENE) NELLA MEDIA VALLE DEL SALTO (RIETI - ITALIA CENTRALE)

Abstract

The middle Salto River Valley is a key area to understand the geologica! evolution of Centrai Italy. The study area lies near the convergence zone between the pelagic Umbrian-Marchean­Sabine domain and the neritic Latium-Abruzzi domain, where a Middle Lias master fault formed and along which the Ancona­Anzio line developed. Two main structural elements, the Olevano­Antrodoco line and the Fiamignano-Micciani fault, divide the area into three sectors, each with its own evolutionary trend and struc­tural style. From west to east they are: the Navegna Unit, the Salto Unit and the Nuria Unit. [...]
