Abstract
A detailed stratigraphical-structural survey combined with classical geological mapping has been performed in the northern Chianti Mts, part of the Northern Apennines Orogen (central Italy). The study area can be subdivided in different tectonic and depositional units: (i) the widely outcropping Tuscan Nappe (middle/late Lias–earliest Miocene), thrusted to the west by (ii) Ligurian units (Cretaceous–Eocene) and unconformably covered by (iii) post-nappe deposits (Pliocene–Pleistocene). The Chianti Mts are structured as a mega-antiformal fold, dissected by WSW-ENE transversal lines and by NNW-SSE normal faults linked with the exhumation of the Northern Apennines Range, developing a basin/ridge structure. As results, (i) a new improved stratigraphic frame is here proposed; (ii) several tectonic and stratigraphic domains have been newly recognised; (iii) a large area characterised by severe internal deformation has been recognised and mapped as an imbricate fan thrust system, linked with transversal lines.
