Loess proportions in slope deposits have rarely been quantified, due to the lack of quantification methods. In this study, we used laser granulometry to analyze grain‐size distributions in slope deposits of a Buntsandstein landscape in central Germany. The consistent loess contents obtained from two independent models corroborate the validity of the calculated loess proportions and the applicability of the new R package EMMAgeo. Yet, some limitations in transferability need to be considered.

简短的交流。利用粒度数据通过激光衍射法定量测定更新世冰山斜坡沉积和全新世冲积层中的黄土比例

由于缺乏量化方法,很少对斜坡沉积物中的黄土比例进行量化。在这项研究中,我们使用激光粒度分析法分析了德国中部Buntsandstein景观的斜坡沉积物的粒度分布。从两个独立的模型获得的一致的黄土含量证实了计算的黄土比例的有效性以及新R包EMMAgeo的适用性。但是,需要考虑可转移性方面的一些限制。
