A provenance study was carried out on loess deposits of SE Poland and Ukraine. For this purpose, loess samples were taken from 18 loess outcrops, and the U-Pb ages of detrital zircons were determined using a SHRIMP IIe ion microprobe. Additionally, studies of the anisotropy of magnetic susceptibility were conducted in the selected sections in order to reconstruct palaeowind directions. Zircons from the youngest loess in SE Poland and western Ukraine yield predominantly Cadomian and younger ages. On the other hand, the pre-Cadomian zircons are the most frequent in the loess from the Dnipro Basin in central and northern Ukraine. While the number of zircon grains analysed does not allow a detailed assessment, the location of the boundary between these two provinces of zircon provenance indicates that the catchment areas of major rivers provided most of the aeolian material. This boundary delimits areas of mountain provenance-river and continental glacier provenance-river transport modes of loess origin. The loess patches located close to the large river valleys were supplied with aeolian material that was blown mainly from the neighbouring riverbeds, as it was inferred from the palaeowind directions. Similar age spectra characteristics for the fine- and coarse-grained zircons demonstrate a significant role for the local transport of detrital material. The same age spectra observed in the loess of different age can indicate a substantial redeposition of sediment.

对波兰东南部和乌克兰的黄土矿床进行了物源研究。为此，从18个黄土露头中提取黄土样品，并使用SHRIMP IIe离子微探针测定碎屑锆石的U-Pb年龄。另外，在选定的部分进行磁化率各向异性的研究，以重建古风向。来自波兰东南部和乌克兰西部最年轻的黄土的锆石主要产于加拿大和更年轻的年龄。另一方面，前乌克兰的锆石在乌克兰中部和北部的第聂伯河盆地的黄土中是最常见的。虽然分析的锆石颗粒数量无法进行详细评估，这两个锆石起源省份之间的边界位置表明，主要河流的集水区提供了大部分的风成物质。该边界划定了黄土起源的山区起源河流和大陆冰川起源河流的运输方式的区域。根据古风向推断，位于大河谷附近的黄土斑块供应了主要从邻近的河床吹来的风沙物质。细粒和粗粒锆石的相似年龄谱特征证明了碎屑物质的局部运输具有重要作用。在不同年龄的黄土中观察到的相同年龄谱可表明沉积物大量重新沉积。该边界划定了黄土起源的山区起源河流和大陆冰川起源河流的运输方式的区域。根据古风向推算，位于大河谷附近的黄土斑块供应了主要从邻近的河床吹来的风沙物质。细粒和粗粒锆石的相似年龄谱特征证明了碎屑物质的局部运输具有重要作用。在不同年龄的黄土中观察到的相同年龄谱可表明沉积物大量重新沉积。该边界划定了黄土起源的山区起源河流和大陆冰川起源河流的运输方式的区域。根据古风向推断，位于大河谷附近的黄土斑块供应了主要从邻近的河床吹来的风沙物质。细粒和粗粒锆石的相似年龄谱特征证明了碎屑物质的局部运输具有重要作用。在不同年龄的黄土中观察到的相同年龄谱可表明沉积物大量重新沉积。因为它是从古风方向推断出来的。细粒和粗粒锆石的相似年龄谱特征证明了碎屑物质的局部运输具有重要作用。在不同年龄的黄土中观察到的相同年龄谱可表明沉积物大量重新沉积。因为它是从古风方向推断出来的。细粒和粗粒锆石的相似年龄谱特征证明了碎屑物质的局部运输具有重要作用。在不同年龄的黄土中观察到的相同年龄谱可表明沉积物大量重新沉积。
