A multidisciplinary study has been led on the Maratta Bassa archaeological site of the VII-VI century B.C., located to north-west of the town of Terni; it has enabled an integrated interpretation of the paleoenvironmental and paleoclimatic evolution of the Terni basin during a time between the Middle Holocene and the historical period.

Abstract
A multidisciplinary study has been led on the Maratta Bassa archaeological site of the VII-VI century B.C., located to north-west of the town of Terni; it has enabled an integrated interpretation of the paleoenvironmental and paleoclimatic evolution of the Terni basin during a time between the Middle Holocene and the historical period. The evolution of the archaeological site of Maratta Bassa was influenced by the water level oscillations of a lake subject to repeated climatically controlled expansion and contraction in a general regressive-trangressive cycle (evolution shrinking). The not particularly deep lake occupied the Terni basin up to historical time with a cyclic history well correlatable with other lakes of central Italy.A stratigraphical sequence a few meters thick has been obtained through the elaboration, comparison and interconnection of geological, geomorphological, mineralogical-petrographical and paleontological evidence with pollen and archaeological data: it is made of alternating lacustrine, fluvial and fluvio-lacustrine deposits. On the basis of analysis and field observations, the succession has been informally subdivided into several units.Pubblicazioni consigliate
