Influence of the Canossa-San Romano Fault on the Quaternary deposits of the Roteglia Terrace (Northern Apennines, Italy)
[En] The Quaternary deposits overlying a strath terrace along the north-western margin of the River Secchia, near the village of Roteglia (Italy), have recorded a complex history influenced by changing hydrological conditions, following the last glacial maximum, and syndepositional tectonic activity related to the Canossa-San Romano fault system. The primary role of climate control appears to have been the back-stepping of fluvial systems, as glaciers thawed and retreated in the adjacent Apennine chain. However, the more dominant control on local sedimentation patterns was deposition within two actively-developing half-grabens formed by the Argontello and Border faults of the Canossa-San Romano system. These faults created barriers to fluvial transport and possible ponding of the Secchia, changing the depositional setting from a through-flowing braided stream system to a mud-dominated meandering channel with abundant overbank deposition or possibly even lacustrine conditions. The barri
