The Amiens-Renancourt 1 site recently yielded one of the most important Upper Palaeolithic human occupations of northern France by the number of flint artefacts and especially by the presence of Venus figurines. All the material comes from a single archaeological layer located in a tundra gley bracketed by loess units. A multi-proxy study combining a detailed stratigraphy, luminescence and radiocarbon datings and high-resolution (5 cm per sample) grain size and molluscan analyses was therefore carried out to reconstruct and date the associated environmental changes and to determine the exact context of the human occupation. The chronological frame thus established supports the correlations of the archaeology-bearing tundra gley and of an underlying arctic brown soil with Greenland interstadials GI-4 and GI-3. Composition changes in the molluscan population enabled the identification of transitional and optimum phases and sub-phases within these two pedogenetic horizons. A conceptual correlation model linking molluscan phases with millennial-scale variations of Greenland ice-core and Sieben Hengste speleothem climate records is proposed. The Human occupation appears contemporaneous to the end of the stadial–interstadial transition of GI-3. Synchronous in Amiens-Renancourt 1 and Nussloch, subsequent micro-gleys may also result from a regional/global forcing. Such a level of detail is unprecedented in a loess sequence.

来自 Amiens-Renancourt 1 旧石器时代晚期遗址（法国索姆）的软体动物组合揭示了末次冰期黄土的内部环境变化

Amiens-Renancourt 1 遗址最近因燧石制品的数量，尤其是维纳斯雕像的存在，成为法国北部旧石器时代晚期最重要的人类职业之一。所有的材料都来自一个单一的考古层，位于由黄土单元包围的苔原地带。因此，进行了一项结合详细地层学、发光和放射性碳测年以及高分辨率（每个样品 5 厘米）粒度和软体动物分析的多代理研究，以重建相关环境变化并确定其年代，并确定人类的确切背景职业。如此建立的年代框架支持了具有考古意义的苔原格莱和下层北极棕色土壤与格陵兰岛间隙 GI-4 和 GI-3 之间的相关性。软体动物种群的组成变化能够识别这两个成土层内的过渡阶段和最佳阶段以及亚阶段。提出了将软体动物阶段与格陵兰冰芯和 Sieben Hengste speleothem 气候记录的千年尺度变化联系起来的概念相关模型。人类占领似乎与 GI-3 的场间 - 场间过渡同时结束。在亚眠-雷南古 1 和 Nussloch 中同步，随后的微格莱也可能由区域/全球强迫引起。这样的细节水平在黄土序列中是前所未有的。提出了将软体动物阶段与格陵兰冰芯和 Sieben Hengste speleothem 气候记录的千年尺度变化联系起来的概念相关模型。人类占领似乎与 GI-3 的场间 - 场间过渡同时结束。在亚眠-雷南古 1 和 Nussloch 中同步，随后的微格莱也可能由区域/全球强迫引起。这样的细节水平在黄土序列中是前所未有的。提出了将软体动物阶段与格陵兰冰芯和 Sieben Hengste speleothem 气候记录的千年尺度变化联系起来的概念相关模型。人类占领似乎与 GI-3 的场间 - 场间过渡同时结束。在亚眠-雷南古 1 和 Nussloch 中同步，随后的微格莱也可能由区域/全球强迫引起。这样的细节水平在黄土序列中是前所未有的。
