“…The Sr-isotope ratio decreased gradually from 0.708235 to 0.707026 from the Middle Permian to Early Permian in the study area, following the Sr-isotope evolution curve elsewhere that also gradually decreased during this period (Veizer et al, 1999;McArthur et al, 2001McArthur et al, , 2012. The Srisotope data in the middle stage of the Late Permian gradually increased from 0.707026 to 0.707255 in the study area, agreeing with 87 Sr/ 86 Sr values elsewhere that also tended to increase steadily during this period (Veizer et al, 1999;McArthur et al, 2001McArthur et al, , 2012, with 87 Sr/ 86 Sr values being linearly correlated with time (Veizer et al, 1999;Williamson et al, 2012;Liu et al, 2013;Ye et al, 2015). The Sr-isotope ratio increased sharply from 0.707255 to 0.707728 at the end of the Late Permian and at the turn of the PTB, just as the curve determined elsewhere (Veizer et al, 1999;McArthur et al, 2001McArthur et al, , 2012Shen and Mei, 2010).…”

“…The composition and evolution of the Sr isotopes of marine sediments (carbonates, sulfates, phosphates, etc. ), which stand as proxy for the original seawater, are not only important means for the study of major global geological events (Derry and France-Lanord, 1996;Goddé ris and Veizer, 2000;Huang et al, 2008;Song et al, 2015;Wierzbowski et al, 2017) and stratigraphic correlation (Huang and Zhou, 1997;Veizer et al, 1997;McArthur et al, 2001McArthur et al, , 2012Huang et al, 2002aHuang et al, , 2008Huang et al, , 2011Liu et al, 2013;Mutterlose et al, 2014), but also are one of the most effective tools for determining the age of marine sediments, and there are numerous successful age determination examples (Hess et al, 1989;McArthur et al, 1994McArthur et al, , 2001Dingle et al, 1997;Denison et al, 1998;Walter et al, 2000;Melezhik et al, 2001;Gleason et al, 2002;Ray et al, 2003;Huang et al, 2005b;Liu et al, 2013;Ye et al, 2015).

The calibration of sedimentary rock absolute dates is one of the difficulties in sedimentological and stratigraphic research. Since strontium (Sr) resides in seawater much longer (≈10 6 a) than the seawater intermixing time (≈10 3 a), the Sr isotopic composition of global seawater is uniform at any time and results in a stable system throughout geological history, based on which a global Sr isotope composition dating database has been established for age-calibration of marine strata. The Permian stratigraphic sections in the northern part of the Upper Yangtze block, southern China, record continuous marine sediments with clear stratigraphic boundaries and is suitable for stratigraphic dating of Sr isotopes. Based on sampling and Sr isotopic compositions of Permian carbonate strata in the northern part of the Upper Yangtze, a Permian Sr isotope evolution curve was established. According to the basic principles of Sr isotope stratigraphy, the global Strontium isotope age database can be used to calibrate the Permian stratigraphic dates in the northern Upper Yangtze. The results show that the Sr isotope evolution curves for the marine carbonate rocks in the Permian stratigraphic section of the Upper Yangtze present a decreasing trend from the mid-Qixia stage (P 2 ) to the mid-Wujiaping stage (P 3 ), and then rise from the middle Wujiaping stage to the end of Changxing stage (P 3 ). When the Permian Sr-isotope evolution curve is compared with the global Sr isotope evolution curve in the northern Upper Yangtze, the two are consistent in their long-term evolutionary trend, indicating that Permian global geological events are important controlling factors for the composition and evolution of Sr isotopes. The 87 Sr/ 86 Sr value decreased gradually in the background of large-scale regressions at the turn of middle to late Permian period, revealing that the Emeishan basalt eruption occurred near the Maokou/Wujiaping boundary (GLB). Srisotope stratigraphy dating was performed on the boundaries of the Qixia Formation/Maokou Formation, Maokou Formation/Wujiaping Formation (GLB), Wujiaping Formation/Changxing Formation (WCB) and the Permian/Triassic (PTB) using the Global Strontium Isotope Age Database. The results are 270.4 Ma, 261.2 Ma, 254.5 Ma and 249.7 Ma, respectively. Based on this, the eruption age of the Emeishan basalts is defined at about 261.2 Ma., which is more coincident with that acquired from other previous dating methods on the eruption age of the Emeishan basalts, and therefore proves that the application of Sr isotopic stratigraphy to dating marine sedimentary units is an effective method.

“…Well‐preserved authigenic micrite and conodont apatite are recommended as the best material for global 87 Sr/ 86 Sr correlation because of its local ambiance‐irrelative nature (Korte & Ullmann, 2016; Veizer et al, 1997). However, 87 Sr/ 86 Sr of marine carbonates could be also partially affected by local provenance and diagenesis (Diener et al, 1996; Tackett et al, 2014), although globally correlatable 87 Sr/ 86 Sr measurement on a marine‐water‐balanced authigenic carbonate could be analyzed after physical–chemical pretreatment (NH 4 Cl‐NH 3 , and NH 4 Ac‐HAc buffer) (Wang et al, 2011; Ye et al, 2015). Any recorded environmental information of a sedimentary sequence includes the global impacts and the local depositional fingerprint (Brennan et al, 2016; Wang et al, 2011; Ye et al, 2015).…”

Chemostratigraphy based on various proxies has been well developed in recent decades for stratigraphic correlation by higher resolution, gap‐less sampling, and environmental records. At present, various types of samples are measured quantitatively in higher accuracy and wider application than traditional biostratigraphy. Even the benthonic index fossils are widely replaced by pelagic data for biostratigraphic correlation, fossil gaps also could cause data break in a section. However, chemostratigraphy remains challenge as its data from sediments is to resolve mixtureof local depositional environment and global correlatable signal. How to separate these two parts and extract the local imprints free from the mixture is the subject of this study. An isochronlines is a newly introduced auxiliary line for the globally correlatable signal extraction from the mixture signals. An isochronline is a virtual synchronous line on plane of an equal depositional environment, and can evaluate the global signal unlike the chemostratigraphic data that provides environmental records. Based on the data obtained from lateral stratigraphic investigation along a bed strike, or from grid mapping on a wide‐open outcrop of a bedding plane, or on a surface of a lithological unit, the facies‐independent chemostratigraphic proxies could be extracted. A set of methods was designed including lateral profiling and grid mapping on the outcrop to extract the facies‐independent geochemical signal for global correlation based on isochronlines identification, and an exception of the Walther's law of facies was revealed. Meanwhile, the author presents examples to avoid misleading of the global chemostratigraphic correlation based on isochronline analysis. This method included measurement of two‐wing lateral‐vertical strata, determination of non‐lithological lens from geochemical abnormities of diagenesis, and microhabitat. An example from Laibin Auxiliary boundary Stratotype Section and Point of Lopingian‐Guadalupian of Permian was measured by grid mapping, that revealed the isochronlines, extracted facies‐independent geochemical proxies for global correlation, and hidden geochemical lenses.

“…Approximately 7 million years prior to the P‐Tr extinction, a major biotic crisis, associated with global sea‐level fall, oceanic anoxia, and the volatile Emeishan flood basalt (EFB) eruption are well recorded in the Guadalupian–Lopingian (G‐L) (middle‐Late Permian) transition, and they are also marked by abnormal geochemical imprints (Chen, George, & Yang, 2009; Chen et al, 2019; Huang et al, 2019, 2019; Jin, 1993; Jin et al, 2006; Jin, Zhang, & Shang, 1994; Kaiho et al, 2005; Shen et al, 2018; Stanley & Yang, 1994; Wang, Cao, & Wang, 2004; Wignall et al, 2009, 2009; Xu, Chung, Shao, & He, 2010; Zhou et al, 2002). Although controversies remain on the pattern and cause of biotic mass extinction near the G‐L boundary (GLB) (Lai et al, 2008; Liu et al, 2013; Shen et al, 2018; Shen & Shi, 2002; Ye et al, 2015), some extreme environmental events are well revealed from the GSSP Penglaitan and Auxiliary Stratotype Section and Point (ASSP) at Tieqiao of Laibin area, including a loss of shallow habitats due to global regression (Chen et al, 2009; Hallam & Wignall, 1997; Wang et al, 2004; Wignall, Sun, et al, 2009; Wignall, Vėdrine, et al, 2009), the EFB eruption (Bagherpour et al, 2018; Courtillot, Jaupart, Manighetti, Tapponnier, & Besse, 1999; Huang, Chen, Wignall, et al, 2019), explosive volcanism and cooling (Ali, Thompson, Song, & Wang, 2002), the Kamura Event (Isozaki, Kawahata, & Ota, 2007), oceanic anoxia (Isozaki, 1997; Kaiho et al, 2005; Zhang et al, 2015), and a catastrophic methane outburst with low atmospheric oxygen (Retallack et al, 2006).…”

Deep‐time chemostratigraphy provides important data for stratigraphy and palaeoenvironmental reconstruction. Geochemical analysis for the same proxy from the same outcrop section, however, often results in different data among various researchers. The dispute was ascribed to inappropriate screening of samples weathering, pre‐treatment, and analytical methods. An outstanding example is that a great variation of 1–3‰ in δ13CVPDB values from the same horizons at Auxiliary Global Stratotype of Section and Point for the Guadalupian–Lopingian (G‐L) boundary in Tieqiao, Laibin, South China was obtained by various research groups. The Walther's Law of Facies suggests that such differences in analytical results may be due to the diachronism of samples measured in high‐resolution stratigraphy. Although lithology and broad sedimentary facies are the same in a lithostratigraphic unit, heterogeneous distribution of bioclastics, δ13Corg, provenances, trace elements, and age‐controlling geochemical signals might have printed on sediments within the same bed. Here, we verified the variations by grid mapping and sampling, a new method for high‐resolution chemostratigraphy, and this practice is applied to the auxiliary GSSP at the Tieqiao section. A total of nine parallel columnar sections from the upper Guadalupian to lowest Lopingian were measured and sampled. In addition, four lateral profiles along four beds were also sampled, and two of them are close to the lower part of the section (upper Guadalupian) and near the G‐L boundary, respectively. These analytical results are plotted along the coordinate of X–Y axis and form the grid mapping on the outcrop. Contour maps of various proxies (i.e., CaO%, total Fe%, and δ13Ccarb) based on the grid mapping were constructed on the outcrop, instead of single excursions of various geochemical proxies throughout the upper Guadalupian to lowest Lopingian. The results show different negative excursions of δ13Ccarb coinciding with biotic extinction near the G‐L boundary and answered the differences of proxy reported in previous studies. Grid mapping of various proxies shows general trends of the proxies on the outcrop; however, there are invisible beddings across lenses in dozens meters size of geochemical abnormal. Analytical data of the same proxy from the same horizons at different columnar sections may present different excursions if sampling on the abnormal lenses or not. This is why the data are different among various studies when different columnar sections were sampled. Various lenses of geochemical abnormal which may be linked tectonic controlled diagenesis, and microhabitat et al., and resulted in the bias from different columnar sections were sampled.
