Zerbrochene Höhlensinter und Kryocalcite als Indikatoren für eiszeitlichen Permafrost im Herbstlabyrinth-Adventhöhle-System bei Breitscheid-Erdbach (N-Hessen)
Abstract:
Speleothem fragments and calcite crystal sands are indicative of the spectacular fragmentation pattern of the central stalagmite of the „Weihnachtsbaum-Halle“ in the Herbstlabyrinth-Advent cave system near Breitscheid-Erdbach (northern Hesse). The fractures are oriented perpendicular and parallel to subparallel to the speleothem layering and were caused by freeze-thaw weathering. According to the trace-element and stable isotope composition the calcite crystal sands formed under cold conditions. The youngest generation of cryogenic calcites, dated to 23–24 ka by U/Th, is indicative of slow freezing of cave waters after the Weichselian Interstadial no. 3 and shows ?13C values from –1.0 to –3.1 ‰ and ?18O values from –13.7 to –17.3 ‰. Based on the dominant occurrence of the rhombohedral crystal type in the crystal sands we introduce a genetic model of a deepening permafrost soil. The multiphase speleothem fracturing and occurrence of cryogenic calcite suggest an extended period of formation during the Weichselian of the studied stalagmite (the age of the top of stalagmite below the oldest cryogenic calcites is 75.8 ka). The repeated combination of freeze-thawweathering of speleothems and the for - mation of cryogenic calcites represents a new indicator for the decoding of the interstadial/stadial transitions during the Weichselian ice age in the periglacial area of central Europe.
