Biochronology of the Mugello intermontane basin (Northern Apennines, Italy)

Abstract

The fluvio-lacustrine succession of the Mugello Basin developed in two main sedimentary phases. During the first (the fluvio-lacustrine phase), the basin hosted a lake, along whose shores fan delta sands and gravels accumulated. The quieter areas were marshy, and peat bogs formed. During the second (the fluvial phase), a terraced alluvial succession developed. A revision of some of the fossil material from the basin has allowed the identification of distinct faunal assemblages, and the attribution of the fluvio-lacustrine sedimentation to the early Pleistocene (Tasso-Farneta F.U.). It has instead proven impossible to determine if the deposition of the fluvial phase began during the early or middle Pleistocene.
