• Resumen

  • In order to reveal evidence for rapid, short-term climate fluctuations on the Iberian Peninsula during the Late Quaternary, we performed a multi-parameter study of the 67-m long sediment core (BAN II) from Lake Banyoles (NE Spain). Our investigation included non-destructive sediment-physical, geochemical and optical methods to identify proxies which are indicative for variability in sedimentology which allude to changes in the environment. According to our age control based on AMS-14C, Useries and tephra from the La Garrotxa volcanic field our sedimentary sequence splits up into 52 m Pleistocene lacustrine deposits and approximately 15 m Holocene sediments on the top. The geochemical analyses revealed proxies (e.g., K/Ca) in the karstic system for climate variability during the Last Glacial. We attributed an increase in K/Ca to more terrigenous input into the lake. Under assumption of our U-series ages the peaks are supposed to represent the influence of Heinrich Events (HE 0-5) in northeast Iberia.
