Analisi polliniche di depositi lacustri delle pendici del M. Vulture in Basilicata

Abstract

Abstract Pollen analysis of lake sediments on Mt. Vulture in Basilicata (Southern Italy).—A marshy sediment, about 7 meters thick, containing fossil pollen, has been discovered in a little lake of volcanic origin on a slope of Mount Vulture in Lucania at 656 m above sea level. The sediment shows four distinct layers from the top to the bottom. The deepest layer, from 7 to 5.75 m, consisting of clay containing Betula and Ostrya, indicates a rather arid climate; the next layer, from 5.75 to 3.75 m, made up of mud rich in organic substance and containing pollen of Fagus and Abies, is witness of a damp and warmer climate; the following layer, from 3.75 to 2.25 m, with clay containing Betula, Ulmus, Ostrya and Corylus suggests a return to a more arid climate; lastly, the upper layer, from 2.25 m to the surface, with marshy mud rich in organic substance and pollen of plants with greater water requirements leads us to think of a return to a damper climate.
