“…In the Penglaitan Section, three ammonoid zones (the Prototoceras-Konglingites, the Etoushanoceras-Jinjiangoceras and Shevyrevites zones) are recognized in the Clarkina orientalis Zone (Ehiro and Shen, 2010). The PrototocerasKonglingites Zone is equivalent to the AnderssonocerasPrototoceras Zone of Zhao et al (1978); and the Etoushanoceras-Jinjiangoceras and Shevyrevites zones probably represent the uppermost zones of the Wuchiapin- Mei et al (1994Mei et al ( , 1998aMei et al ( , 1998b, Mei and Wardlaw (1996), Chen et al (2008) and our recent studies.

“…Five Lopingian conodont zones, the Clarkina bitteri-C. liangshanensis, C. leveni and C. orientalis zones for the Wuchiapingian, and the Clarkina subcarinata-C. wangi Zone and C. deflecta-C. changxingensis Zone for the Changhsingian were initially established (Wang and Wang, 1981;Zhao et al, 1981;Wang, 1993). This Lopingian zonation has been greatly refined based on subsequent biostratigraphic and taxonomic studies (Kozur, 1990(Kozur, , 2004(Kozur, , 2005Mei et al, 1994Mei et al, , 2004Mei et al, , 1998aMei et al, , 1998bMei and Wardlaw, 1996;Shen and Mei, 2010).…”

“…The six Changhsingian conodont zones are mainly revised from Mei et al (1998a), recent studies by Zhang et al (2007) and Chen et al (2008), as well as our unpublished materials. The zones include in ascending order the Clarkina wangi, C. subcarinata, C. changxingensis, C. yini, C. meishanensis and C. zhejiangensis zones; the C. bachmanni Zone spans a short interval at the base of the C. yini Zone in South China.…”

High‐resolution Lopingian (Late Permian) timescale of South China

et al. 2010

The Lopingian represents the last epoch of the Palaeozoic Era and is bracketed by two severe biotic mass extinctions associated with dramatic environmental changes. The Lopingian Epoch lasted about 7 millions years and was also bracketed by large volcanic eruptions with the Emeishan volcanics at the base and the Siberian traps at the top. Considerable data have accumulated recently and in this paper we attempt to summarize these findings in a high-resolution Lopingian (Late Permian) timescale that integrates currently available multiple biostratigraphic, isotope chemostratigraphic, geochronologic and magnetostratigraphic data. In South China at least 13 conodont zones, multiple polarity zones and large carbon isotope fluctuations in the Lopingian are recognized and provide the high-resolution calibration that is essential to study this Late Permian interval characterized by Earth's largest biotic extinction. We also present a global correlation chart for the marine Lopingian Series.

High-resolution stratigraphy of the Changhsingian (Late Permian) successions of NW Iran and the Transcaucasus based on lithological features, conodonts and ammonoids

Abstract. The Permian-Triassic boundary sections in northwestern Iran belong to the most complete successions, in which the largest mass extinction event in the history of the Earth can be studied. We investigated the Changhsingian stage in six sections in the area of Julfa (Aras Valley) for their lithology, conodonts and ammonoids. Revision of the biostratigraphy led to the separation of 10 conodont zones (from bottom to top Clarkina orientalis-C. subcarinata interval zone, C. subcarinata, C. changxingensis, C. bachmanni,

Evidence for sea‐level falls in the Permian‐Triassic transition in the Ziyun area, South China

The sedimentology of three sections showing the Permian-Triassic (P-T) transition on an Upper Permian reef in Ziyun, Guizhou Province, southwest China provides evidence of sea-level fall in this area. The P-T transition in the Gendan section, which covers a reef-front sequence, contains a subaerial exposure surface and various desiccation cracks (including rolled-up chips, in-chip cracks, pyramid cracks, vertical cracks and sheet cracks), indicating sea-level falls. The P-T transition in the Shitouzhai section, which covers a reef-core sequence, contains three micritic beds with abundant pseudomorphs of tabular gypsum crystals replaced by calcite. The underlying centimetres of deposits are composed of fine-crystalline dolostone, and have a sharp contact with the underlying reef-core facies. The association of gypsum pseudomorphs and fine-crystalline dolostone suggests an origin related to a supratidal evaporative environment. The P-T transition in the Tanluzhai section, which covers a back-reef sequence, is fine-crystalline dolostone, and shows a laminated algal structure indicating tidalflat environments. The middle part of the dolostone interval has become a collapse breccia composed of dolostone fragments and a matrix of micrites or crustose multi-generation calcite cements. The formation of the collapse breccia is interpreted to be related to the dissolution of the evaporite interbeds originally present between the thin dolostone beds. The formation of the evaporite deposits requires a supratidal condition.
