“…As has been the case in other countries, most of the past conodont investigations in China (e.g., An 1981, 1985, Chen & Zhang 1984, An & Ding 1985, Ni & Li 1987, An & Zheng 1990, Gao 1991, Wang & Bergström 1995, Wang et al 1996, Wang & Zhou 1998, Zhang 1998, Zhao et al 2000, Zhen et al 2007, 2009, Chen et al 2011 have had a biostratigraphic and taxonomic focus. Other aspects of conodont research, such as palaeoecology and conodont animal palaeobiology, have been dealt with in far fewer studies.…”

“…As such, the influence of terrigenous clasts on the research samples is ruled out. The samples have positive and negative δ 13 C PDB values, most of which are negative and range from −1.60‰ to 0.50‰. The negative δ 18 O PDB values of the samples only vary between −9.00‰ and −2.00‰.…”

“…Derry et al [25] argue that dolomitization is not a precondition of carbonate rocks that are unaffected by diagenesis. The δ 13 C values of carbonate rocks represent carbon isotope contents at the Proto-Oceanic level when their δ 18 O PDB values are more than −10‰ [26]. These carbon isotope contents are associated with sea level changes and vary between −5‰ and 5‰.…”

This study analyzes the variations in trace element contents and ratios, the distribution patterns of rare earth elements, and the sedimentary environment and its evolution in the Early Ordovician. In particular, the analysis is based on measured section of the Qingjiang Village located in Nangao Town, Danzhai County, Guizhou Province. The analysis also considers thin sections and the characteristics of C, O isotopes. The lower part of the Tongzi Formation has a simple lithology and mainly consists of light gray to gray thin-medium bedded muddy dolomite and dolomicrite with a few dolarenites and dolorudites. The upper part of this formation includes gray thin-medium bedded fine crystalline dolomite and gray massive bioclastic limestone. Only a fraction of gray massive fine crystalline limestone, sparry calcarenite, and calcirudite are on top of the upper part. The Honghuayuan Formation is generally composed of light gray to gray medium-thick bedded or massive bioclastic limestone, reef limestone, and calcarenite with a few sandstones at the bottom. The δ 18O PDB values of 18 samples are less than −11‰; in addition, the Pr/Pr* and Ce/Ce* ratios are greater and less than 1, respectively. These data reflect a sedimentary environment. The lower part of the Tongzi Formation might have been formed in an evaporite platform, which was then transformed into a restricted one, which featured a dry climate, a shallow water depth, and an insufficient amount of oxygen. By contrast, the upper part of the formation was deposited in an open platform, which featured a humid climate and relatively increased water depth and reducibility. During the sedimentary period of the Honghuayuan Formation, the water energy further increased, the climate became humid, the water depth increased, and the reducibility increased. Correspondingly, the sedimentary environment, which originally comprised littoral facies that slowly developed into an open platform and into a platform marginal bank, gradually evolved into a platform How to cite this paper:

“…In the Honghuayuan Section, P. honghuayuanensis occurs abundantly in the top part of the Honghuayuan Formation, but neither P. honghuayuanensis nor O. communis was recovered from the basal part of the overlying Meitan Formation. However, in the Ganxi Section of Yanhe, P. honghuayuanensis was recovered from the very top of the Honghuayuan Formation (Zhen et al 2005(Zhen et al , 2007b, and O. communis was reported from the basal part of the overlying Meitan Formation (Zhen et al 2007a). As both species were recorded within a very short interval in the Ganxi section, it is considered likely that they might have been adapted to different environments, in particular water depth or temperature.…”
