Eiszeitliche Klimadynamik im Spiegel eines Stalagmiten aus dem Hölloch (Bayern/Vorarlberg)
Abstract:
A speleothem recovered from Hölloch Cave located at the border between Germany and Austria that was deposited during the Last Glacial shows prominent layers of silt and clay documenting episodes of extensive cave flooding. Such intermittent flooding events are not known from the modern cave system, although some galleries are situated in the epiphreatic zone. According to Uranium-Thorium age determinations of 13 calcite subsamples, stalagmite growth started around 62 kyr (= 62,000 years) before present and ended 40 kyr ago, i.e. the only 41 cm-tall stalagmite comprises a time interval of ca. 20 kyr during the Last Glacial. Fin-like extensions in the lower part of the stalagmite document calcite deposition competing with the aggradation of coarsegrained sand. U-Th dates in combination with the internal structure of the stalagmite constrain the age of this period of clastic sedimentation by the cave stream to between 62 and 46 kyr. In addition, the stalagmite also reveals several layers of silty clay documenting growth interruptions as a result of prolonged flood events. Highresolution oxygen isotope measurements along the stalagmite growth axis highlight abrupt alternations of warmer and colder climate conditions during the Last Glacial period. The flooding events occurred preferentially at the end of the relatively short warm phases (interstadials) and at the onset of the subsequent cooling episodes (stadials).
