Resumen

The sedimentary evolution of Sanabria Lake (Zamora province, NW Spain) is reconstructed based on 4 kullenberg cores and 3 short cores. The longest core (9 m long) in the deepest (51 m) eastern subbasin reached the laminated and banded clastic proglacial lacustrine sediments deposited when the watershed was still glaciated. Basal 14C AMS dating (ca. 26 ka BP) indicates that the terminal morraine complex deposited prior to the global LGM. A high resolution study including magnetic susceptibility and XRF core-scanner geochemistry show millennial andcentury scale cycles in Lateglacial and Holocene organic-rich sediments. Calibration studies including 20 year long series of limnological data, short sediment cores, meteorological and land-use changes data are in progress
