THE PROSERPINE STALAGMITE (HAN-SUR-LESSE CAVE, BELGIUM): PRELIMINARY ENVIRONMENTAL INTERPRETATION OF THE LAST 1000 YEARS AS RECORDED IN A LAYERED SPELEOTHEM

International audience ; A two meters long core from the big "Proserpine" stalagmite of the Han-sur-Lesse cave, deposited from 1800 (±75) U/ years BP to recent, displays seasonal layering with two layers deposited during one year. Growth rates of up to 2.1 mm per year are observed. Similar changes are observed in the speleothem fabric, the δ 18 O and δ 13 C isotopic compositions and the growth rate along the longitudinal axis, suggesting common climatic and/or environmental controls. A fi rst multi proxy approach is attempted, in order to interpret the constructed time-series in terms of chang... Mehr ...
