Recent improvements in geochemical techniques have \r\nenabled us to analyze climate-influenced deposits at high temporal \r\nresolution so that hitherto unrecognized environmental conditions \r\nmay be identified. Stable H, C and O isotope analyses on carbonate \r\nand inclusion water have been combined with multicollector \r\ninductively coupled plasma mass spectrometry (MC-ICP-MS) age dating \r\nand laser-ablation ICP-MS trace element analyses on a stalagmite \r\nfrom southern Hungary. The study reveals significant changes in \r\nchemical and isotopic compositions of the speleothem between approx. \r\n3800 and 3500 years BP ('Before Present') indicating coupled changes \r\nin the temperature and precipitation regime under which the \r\nspeleothem formed. Stable isotopic and trace element correlations \r\nwithin this time period correlate with similar studies of stalagmites \r\nof comparable age from the Alpine-Mediterranean region. Our studies \r\nsuggest that traces of deposition of volcanic dust, possibly related \r\nto the Thera eruption of Santorini (Greece) ca. 1650 BC (~3650 BP), \r\nand environmental changes can be detected at a distance of several \r\nthousand kilometers. \r\n","author":null,"citation":"Siklósy, Z., A.
