I propose to investigate the potential of the Herbstlabyrinth cave system, Rhenish Slate Mountains, Breitscheid, Germany, for palaeoclimate studies and to reconstruct Holocene and Late Glacial climate variability in central Germany based on precisely dated speleothems. The Herbstlabyrinth represents an interesting for high-resolution palaeoclimate studies for several reasons: (i) an extensive cave monitoring program has been established using initial funding of the University of Mainz. This supports investigation of the processes affecting speleothem climate proxies and a robust interpretation in terms of climate variability. (ii) Our preliminary study has documented speleothem growth during the Late Glacial period. Speleothem growth during this relatively cold and dry period is extraordinary for this region and provides the opportunity to study Late Glacial climate variability in Germany based on speleothems. (iii) Winter rainfall oxygen isotope values in the cave region have been shown to be strongly positively correlated with the North Atlantic Oscillation (NAO). Thus, the δ18O signals recorded in the speleothems may reflect past NAO variability. The already established cave monitoring program will be continued throughout the proposed project in order to support a robust interpretation of the climate proxies. We will date several speleothems from the Herbstlabyrinth by high-precision MC-ICPMS U-series dating. Past climate variability will be reconstructed using high-resolution stable oxygen and carbon isotopes as well as trace elements in several coeval speleothems.

我提议调查德国布赖特沙伊德莱尼什板岩山的 Herbslabyrinth 洞穴系统用于古气候研究的潜力，并根据精确年代的洞穴化石重建德国中部全新世和晚冰期气候变化。草本迷宫代表了高分辨率古气候研究的一个有趣的领域，原因如下：（i）利用美因茨大学的初始资金建立了广泛的洞穴监测计划。这支持对影响洞穴气候代理的过程进行调查，并对气候变化进行强有力的解释。 (ii) 我们的初步研究记录了晚冰期时期洞穴生物的生长。在这个相对寒冷和干燥的时期，洞穴生物的生长对于该地区来说是非同寻常的，并为基于洞穴生物研究德国晚冰期气候变化提供了机会。 (iii) 洞穴地区冬季降雨氧同位素值已被证明与北大西洋涛动 (NAO) 呈强正相关。因此，洞穴中记录的 δ18O 信号可能反映了过去的 NAO 变化。已经建立的洞穴监测计划将在整个拟议项目中继续进行，以支持对气候代理的有力解释。我们将通过高精度 MC-ICPMS U 系列测年来确定 Herbslabyrinth 中的几个洞穴化石的年代。过去的气候变化将利用高分辨率的稳定氧和碳同位素以及几个同时代洞穴中的微量元素来重建。
