In our original study, we used sediment element contents, a standardized mesoscale grid approach and a geochemical-statistical fingerprinting mixing model to reconstruct Holocene hydrosedimentary processes in the catchment of the Weiße Elster River in Central Germany. Tomas Matys Grygar pointed out in his constructive comment on our study that sediment element contents result from the interplay of sediment provenance, weathering processes and grain-size effects. We should note that we did not use the geochemical-statistical fingerprinting mixing model as a black box, choosing to rely instead on extensive geomorphological, lithological and geochemical preliminary work and findings, which we would like to take up again in this correspondence. For further validation of our original findings, we have carried out new grain-size-specific analyses of element ratios from Weiße Elster overbank silt-clay deposition (German: Auelehm) and new grain-size analyses of floodplain deposits from Weiße Elster tributaries. These new data are discussed and are made available in the supplementary online material.
在我们最初的研究中，我们使用了沉积物元素含量、标准化中尺度网格方法和地球化学统计示踪混合模型，以重建德国中部 Weiße Elster 河流域全新世水-沉积物过程。Tomas Matys Grygar 在对我们研究的建设性评论中指出，沉积物元素含量是由沉积物源、风化过程和粒度效应共同作用的结果。我们应该注意到，我们并没有将地球化学统计示踪混合模型视为一个黑箱，而是选择依赖于广泛的地貌、岩性和地球化学初步工作和发现，我们希望在本次通信中再次探讨这些问题。为了进一步验证我们最初的发现，我们对 Weiße Elster 漫滩淤泥-粘土沉积（德国称 Auelehm）中的元素比值进行了新的粒度特异性分析，并对 Weiße Elster 支流的泛滥平原沉积物进行了新的粒度分析。这些新数据在补充在线材料中进行了讨论和提供。
