Western Central European Loess-Palaeosol-Sequences (LPS) provide valuable terrestrial records of palaeoenvironmental conditions, which formed in response to variability in the North Atlantic climate systems. Over the last full glacial cycle (∼130 ka), climate oscillations within these systems are best documented in deep sea- and ice cores; the responses of terrestrial systems are not yet fully understood. A better understanding of metabolism governing input and output variables of organic- and inorganic C pools is, however, crucial for investigating landscape-atmospheric feedback processes and in particularly, for understanding the formation of calcareous LPS as environmental archives. Here we quantify the contributions of primary carbonates (PC) and secondary carbonates (SC) to the overall inorganic carbon pool down a LPS at the Schwalbenberg site, based on the natural abundance ratio of stable carbon isotopes (δ¹³C) and contents of the organic- and inorganic C pools. This facilitates detailed insights into the carbonate metabolism and hence, loessification and percolation processes. PC accumulate predominantly in cold phases during periods of reduced biological activity and become leached during wetter and warmer periods contemporary with higher rates of SC re-precipitation and total organic carbon (TOC) increases due to enhanced biomass production. We find that mineral dust input is most significant during stadials, as well as toward the end of warmer interstadials, characterised by gradual cooling back to stadial conditions. Pedogenesis in the Schwalbenberg LPS kept pace with surface accumulation of mineral dust. This indicates that palaeosols are of accretionary nature, which gives raise to the idea of incorporation of former topsoils in preserved subsoil horizons. Our study decodes fundamental aspects of the link between atmospheric dust circulation and terrestrial records in western Central Europe. In addition, interdependencies between factors governing the regional moisture budged and LPS can be reconstructed in a more holistic way than before.

中欧西部的黄土古土壤序列（LPS）提供了有价值的陆地环境条件的陆地记录，该条件是响应北大西洋气候系统的变化而形成的。在最后一个完整的冰川周期（〜130 ka）中，这些系统内的气候振荡最好记录在深海和冰芯中。地面系统的反应尚未完全了解。然而，更好地理解控制有机碳和无机碳库的输入和输出变量的代谢对于研究景观-大气反馈过程，特别是对于了解钙质LPS作为环境档案的形成至关重要。¹³C）以及有机和无机C库的内容。这有助于深入了解碳酸盐的代谢，从而了解黄泥化和渗滤过程。在生物活性降低的时期，PC主要积累在寒冷阶段，而在湿润和温暖的时期，PC会逐渐浸出，这是因为随着生物量产量的增加，SC的再沉淀率更高，总有机碳（TOC）也增加。我们发现，矿物粉尘输入在球场期间以及在温暖的星际末期最显着，其特征是逐渐冷却回到球场状态。Schwalbenberg LPS中的成岩作用与矿物粉尘的表面堆积保持同步。这表明古土壤具有增生性，这就提出了将以前的表层土纳入保留的下层土层中的想法。我们的研究解释了中欧西部大气尘埃循环与地面记录之间联系的基本方面。另外，可以比以前更全面的方式重建控制区域水分萌芽和LPS的因素之间的相互依赖性。
