Geomorphological Evolution

The lower Calore and middle Volturno valleys preserve stratigraphical and morphological evidence and tephrostratigraphic markers particularly suitable for reconstructing the long-term geomorphological evolution of the central-southern Apennines. Aim of our study is to identify the main steps of the Quaternary landscape evolution of these valley systems and to improve knowledge about the relationships between fluvial processes and tectonics, volcanic activity, climatic and human influences. To this purpose, we carried out an integrated geomorphological and chrono-stratigraphical analysis of identified fluvial landforms and related deposits, integrated by 230Th/234U datings on travertines from the Telese Plain area. The study highlighted in particular: (1) fluvial sedimentation started in the Middle Pleistocene (~650 ka) within valleys that originated in the lower Pleistocene under the control of high-angle faults; (2) extensional tectonics acted during the Middle and Upper Pleistocene, driving the formation of the oldest fluvial terraces and alluvial fans, and persisted beyond the emplacement of the Campanian Ignimbrite pyroclastic deposits (~39 ka); and (3) from the late Upper Pleistocene onwards (<15 ka), the role of tectonics appears negligible, while climatic changes played a key role in the formation of three orders of valley floor terraces and the youngest alluvial fans.

Geomorphological Evolution

This study is based on the collection, process and management of the geographical, geological and geomorphological data of the area of the basin of Athens with main objects the construction of a geomorphological map of the study area, the description and the study of the geoshapes that exist and the approach of the geomorphological evolution of the basin. The main erosion forms such as gorges and erosion surfaces are observed in the northern part of the study area at the mountain of Parnitha compare to the deposition forms that we meet in the southern part. As well as landforms like inselberg and alluvial fans give important information for the geomorphological evolution of the basin of Athens.
