摘要：
The research of conodont biostratigraphy and carbon isotope change at the Dawoling section provides basic materials for the exploration of creatures and environment change in the Wuchiapingian-Changhsigian period. The Dawoling section at Yuanjia Town, Jiahe county, Hunan Province, recorded basinal deposition during the Late Permian. The Talung Formation is well-exposed and displays siliceous rock, siliceous limestone, limestone and claystone. Three conodont taxa (one is undetermined) of genus Clarkina: C. wangi, C. deflecta and C. sp. are identified, and these enable the tentative assignment of a C. wangi Zone overlain by a C. changxingensis-C. deflecta assemblage Zone. The Wuchiapingian-Changhsingian boundary (Wuchiapingian-Changhsingian boundary, WCB) is placed at the first occurrence (FO) of C. wangi at the base of bed 11 at this Dawoling section. A rapid negative shift from 2.18‰ to -1.39‰ in carbonate carbon isotope in beds 13-15 correlates well with the Changhsingian GSSP(Global Stratotype Section and Point) section at Meishan in Zhejiang and the Shangsi section of Sichuan. Therefore, this negative excursion could be a regionally correlation horizon in south China. © 2016, Editorial Department of Earth Science. All right reserved.
