U-Pb LA-ICP-MS DATING OF DETRITAL ZIRCON FROM UPPER PERMIAN SANDSTONE OF THE BOYEVAYA GORA SECTION (ORENBURG REGION, SOUTHERN CIS-URALS)
https://doi.org/10.5800/GT-2022-13-2s-0600
Abstract
The first results of U-Pb LA-ICP-MS dating of 150 detrital zircon grains from the Upper Permian sandstone of the Boyevaya Gora section (Orenburg region, the Southern Cis-Urals) are presented. 95 conditional zircon U-Pb isotopic dates form two age peaks – 381 and 529 Ma. It is assumed that clastic material entered the sedimentation basin mainly due to erosion of the Early Hercynian Ural complexes and relics of the Protouralian-Timanian orogen.
