| 英文摘要 | The Penglaitan section, as the Global Stratotype Section for the Guadalupian-Lopingian boundary (GLB), displays continuous deposition with a complete succession of pelagic conodont zones across the GLB. However, there is no reliable radiometric age from the Penglaitan section itself to constrain the GLB. Here, we report SIMS zircon U-Pb ages from two bentonite layers (Bed 7c) in the Penglaitan Global Stratotype Section near the GLB. The sample PL-62-1 yields a weighted mean U-238/Pb-206 age of 257.1 +/- 2.2Ma, and the sample PL-62-2 yields a weighted mean Pb-206/U-238 age of 257.0 +/- 4.2Ma. Therefore, we consider 257.0-257.1Ma as the age of deposition of Bed 7c (the end of the C. postbitteri postbitteri conodont Zone, ca. 86cm above the GLB), and, considering the depositional rate of chert, we suggest 258.6Ma as the age of the GLB.
