Two small annually laminated stalagmites from Zoolithencave (southeastern Germany) grew between CE 1821 and 1970 (Zoo‐rez‐1) and CE 1835 and 1970 (Zoo‐rez‐2), respectively. Trace element concentrations were determined by Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA‐ICP‐MS). Samples for δ¹³C and δ¹⁸O analyses were micromilled on annual and subannual resolution. Soil and host rock samples were analyzed by X‐Ray Diffraction (XRD) and their elemental concentrations determined via inductively coupled plasma optical emission spectrometer (ICP‐OES). Trace element concentrations in the stalagmites show two groups in the principal component analyses: one with Mg, Ba, and Sr and another with Y, P, and Al, respectively. The second group reflects the content of detrital material. Increased weathering of soil minerals seems to have a strong influence on the silicate/carbonate weathering ratio controlling the variability of Mg, Ba, and Sr. Meteorological and Global Network of Isotopes in Precipitation (GNIP) station data were used to calculate the δ¹⁸O values of the drip water (infiltration‐weighted, mean annual, and the mean of the winter precipitation δ¹⁸O values) as well as the corresponding speleothem calcite. The δ¹⁸O values calculated by the infiltration‐weighted model show similar patterns and amplitudes as the measured δ¹⁸O values of the two stalagmites. This suggests that the δ¹⁸O values of speleothem calcite reflect the δ¹⁸O values of infiltration‐weighted annual precipitation, which zis related to mean annual temperature, resulting in a significant correlation between mean annual temperature and the measured δ¹⁸O values of stalagmite Zoo‐rez‐2. This relationship could potentially be used for quantitative climate reconstruction in the future by extending the time series back in time with further stalagmites from Zoolithencave.

Zoolithencave（德国东南部）的两个同时生长的石笋的高分辨率代理记录及其古气候重建的潜力

分别在1821年至1970年（Zoo‐rez-1）和1835年至1970年（Zoo‐rez‐2）分别生长了两个来自Zoolithencave（德国东南部）的小型层状石笋。痕量元素浓度通过激光消融电感耦合等离子体质谱法（LA‐ICP‐MS）确定。样品δ ¹³ C和δ ¹⁸O分析在年度和次年分辨率上进行了微分析。通过X射线衍射（XRD）分析土壤和宿主岩石样品，并通过电感耦合等离子体发射光谱仪（ICP-OES）测定其元素浓度。石笋中的痕量元素浓度在主要成分分析中显示两组：一组分别具有Mg，Ba和Sr，另一组分别具有Y，P和Al。第二组反映了碎屑物质的含量。土壤矿物的风化增加似乎对硅酸盐/碳酸盐风化比来控制的Mg，Ba和高级气象和同位素的降水全球网络（GNIP）的变异性的强烈影响站数据被用于计算δ ¹⁸滴注水的O值（浸润加权，平均年，平均冬季沉淀δ的^18个O值），以及对应的钟乳石方解石。的δ ¹⁸由浸润加权的模型计算O值显示为δ测量的类似的模式和幅度^18个两个石笋的O值。这表明，δ ^18个钟乳石的O值方解石反映δ ^18个浸润加权年降水量，其ZIS意味着每年温度相关的O值，导致年平均温度和δ测量之间的相关性显著¹⁸石笋Zoorez-2的O值。通过将时间序列与Zoolithencave的进一步石笋一起延长，可以将这种关系将来用于定量气候重建。
