At the Willendorf site Upper Paleolithic archeological layers associated to early Aurignacian cultures were found. The environmental conditions of the associated society, potentially co-existing with Neanderthal groups, is still not fully understood. Here, we report on environmental magnetic analyses including anisotropy of the magnetic susceptibility (AMS) carried out on loessic aeolian sediments at the Willendorf site. Data on lineation, foliation and the degree of anisotropy were used to assess depositional and post-depositional magnetic fabric properties and to deduce site-specific environmental processes. Overall, the loess is of aeolian origin and shows magnetic enhancement and magnetic fabric properties similar to those of other European loess geoarchives, but the magnetic mineralogy differs from many ‘dry’ loess sites, insofar as it shows a higher susceptibility during heating. We infer an enhanced neoformation of magnetite during heating due to the presence of organic matter. While at face value the AMS properties are indicative of pure aeolian loess consistent with previous studies, imbrication suggests post-depositional slope movement toward the Danube, which obscures inferences on palaeo-wind direction. It is well possible that these post-depositional magnetic fabric alterations occur at other localities with similar geomorphological settings.

在威伦多夫遗址，发现了与早期奥里尼加文化有关的旧石器时代上层考古学层。可能尚未与尼安德特人团体并存的相关社会的环境条件仍未完全了解。在这里，我们报告了环境磁分析，包括在Willendorf站点的黄土风成沉积物上进行的磁化率各向异性（AMS）。有关线，叶和各向异性程度的数据用于评估沉积和沉积后磁性织物的性能，并推论特定地点的环境过程。总体而言，黄土是风成土的，具有类似于欧洲其他黄土地质档案的磁增强作用和磁性织物性质，但是磁矿物学与许多“干”黄土部位不同，就其在加热过程中表现出更高的敏感性而言。我们推断由于有机物的存在，磁铁矿在加热过程中的新形成增强。尽管从表面上看，AMS的特性表明与以前的研究相一致，纯的风土黄土，但振动表明沉积后的斜坡向多瑙河运动，这掩盖了对古风向的推论。这些沉积后磁性织物的变化很可能发生在其他具有相似地貌设置的地方。振动表明沉积后斜坡向多瑙河运动，这掩盖了关于古风向的推论。这些沉积后磁性织物的变化很可能发生在其他具有相似地貌设置的地方。振动表明沉积后斜坡向多瑙河运动，这掩盖了对古风向的推论。这些沉积后磁性织物的变化很可能发生在其他具有相似地貌设置的地方。
