In order to determine the provenance and age of terrigenous-carbonate stratified units exposed in the region of Bagrush Mountains, Bashkirian uplift, U–Pb dating of detrital zircons from these units has been carried out. A comparison of the data results with analogous data on five stratigraphic levels within the Riphean section of the Bashkirian uplift has shown that the studied sequence should be, most likely, correlated to the uppermost Lower Riphean or the lowermost Middle Riphean.

基于碎屑锆石 U-Pb 测年 (LA-ICP-MS) 结果的巴格鲁什山脉（乌拉尔南部）沉积层序的年龄和地层位置

为了确定巴格鲁什山脉、巴什基尔隆起地区出露的陆源碳酸盐岩层状单元的物源和年龄，对这些单元的碎屑锆石进行了 U-Pb 定年。将数据结果与 Bashkirian 隆起 Riphean 段内五个地层层级的类似数据进行比较，表明所研究的序列最有可能与最上面的下 Riphean 或最下面的中 Riphean 相关。
