Abstract

The Coma de Burg lake (CMB) and the Estanilles peat bog (EST) are two sedimentary records that provide paleoenvironmental information about the Lateglacial-Holocene transition in the central-eastern Pyrenees (Alt Pallars, Lleida). The comparison of the organic matter values (Loss On Ignition) with the pollen records from the two sequences (CMB and EST) indicates that the LOI is more sensitive to the changes in temperature than precipitation. Pollen values reflect the succession of different landscapes, from steppe formations (Artemisia and Poaceae) to forest communities (Pinus, Betula and Corylus). The 6 fluctuations documented by the LOI coincide with the temperature fluctuations in the Northern Hemisphere (Greenland Ice Core Project, GRIP) and mark Bølling, Allerød, Younger Dryas and the Holocene onset as well as later fluctuations.
