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.

我建议研究Herbstlabyrinth洞穴系统，Rhenish Slate Mountains，Breitscheid，德国，用于古气候研究，并基于精确约会过时的脾脏重建德国中部的全新世和晚期冰川气候变化。 Herbstlabyrinth代表了高分辨率古气候研究的有趣，原因是：（i）使用Mainz大学的初始资金建立了广泛的洞穴监测计划。这支持了影响更大的流程，气候代理和在气候变异性方面的强大解释。 （ii）我们的初步研究记录了冰川后期的增长大声。对于该地区的相对寒冷和干燥期，在这个相对寒冷和干燥期间的speleothem生长是基于大声研究德国的晚期冰川气候变化的机会，并且（iii）洞穴区域的冬季降雨同位素值已被证明与北大西洋振动（NAO）相关。这，记录在Speleothems中的Δ18O信号可能反映了过去的NAO变异性。已经建立的洞穴监测计划将在整个拟议的项目中继续进行，以支持对气候代理的强大解释。我们将通过高精度MC-ICPMS U系列约会来约会Herbstlabyrinth的几个speleothems。过去的气候变异性将使用高分辨率稳定的氧和碳同位素以及几个共同speleothems中的微量元素重建。
