AB The different sedimentological, geochemical and geophysical analysis performed in the Montcortéslake sedimentary record (Pre-Pyrenees, Lleida) helps to interpret the sedimentary evolution of this karsticlake during the last 6.000 years. The deposition of lacustrine varves is continuous during, at least, the last3.500 Cal. yr BP. This fine lamination is punctuated by massive clastic facies corresponding to turbiditeevents. A total of 9 litostratigraphic units were recognized corresponding to three different depositionalenvironments that alternate throughout the record; i) a shallow, meromictic lake with very highbioproductivity (unit VI: 6.000- 3.500 Cal. yr BP), ii) a deep, meromictic lake with high bioproductivity(units V, III and I; 3.500-1.250, 500-180 Cal. yr BP and last decades) and iii) deep, meromictic lake withhigher clastic inputs (units IV and II; 1.250-500 and 180 Cal. yr BP- last decades). Several slumps depositshave been recognized within the sequence (units A, B and C)
