Geomorphological features and radiocarbon dating of some Quaternary deposits at Difesella del Trionto (Calabria, Southern Italy)

Abstract

The sedimentary deposits, Pleistocene in age, outcropping at Difesella del Trionto (Calabria) are examined. The main geologic and morphologic characters, along with the results of radiocarbon dating and organic geochemical analysis of some layers rich in organic carbon are reported. The results, strongly suggesting that about 31,000 yr. B.P. a lake formed in the area, are in line with landsliding events which occurred downvalley of Difesella, as it is recorded by several morphologic features. It is inferred that such processes triggered the valley damming, thus determining lacustrine sedimentation.
