Abstracts The results of U–Th–Pb LA-ICP-MS dating of detrital zircons collected from the Permian–Triassic red beds of the Moscow Basin are presented. U–Th–Pb ages of detrital zircons from two samples (Upper Permian and Lower Triassic), which were collected in the vicinity of the P–T boundary in the Zhukov Ravine reference section, show their contrasting provenance. It means that U–Pb detrital zircon geochronology can be used as an additional independent tool for stratigraphic correlation of the Permian–Triassic red beds, at least within the Moscow Basin. The applicability of the method is illustrated by additional constraints on the age of the Nedubrovo member deposits (Vologda Region) with a previously uncertain stratigraphic position: the U–Pb age pattern of the respective detrital zircons suggests their Early Triassic age.

二叠纪-三叠纪红层的地层相关性，莫斯科盆地，东欧平台：第一个碎屑锆石 U-Pb 测年结果

摘要 介绍了从莫斯科盆地二叠纪-三叠纪红层收集的碎屑锆石的 U-Th-Pb LA-ICP-MS 测年结果。在朱可夫峡谷参考剖面的 P-T 边界附近收集的两个样品（上二叠纪和下三叠纪）碎屑锆石的 U-Th-Pb 年龄显示了它们对比的来源。这意味着 U-Pb 碎屑锆石年代学可以用作二叠纪-三叠纪红层地层对比的附加独立工具，至少在莫斯科盆地内是这样。对 Nedubrovo 成员矿床（沃洛格达地区）年龄的额外限制说明了该方法的适用性，该地区以前地层位置不确定：各个碎屑锆石的 U-Pb 年龄模式表明它们的早三叠世年龄。
