“…The type areas for the Chinese regional Upper Devonian and lower Carboniferous chronostratigraphy are in central Hunan and southern Guizhou, South China, respectively (Qie et al 2019a;Wang et al 2019), and represented by mixed siliciclastic and carbonate platform successions with diverse benthic faunas (e.g. brachiopods, rugose, and tabulate corals and foraminifers).…”

The Devonian-Carboniferous transition is marked by major perturbations to the Earth's climate system and marine redox conditions, a first-order mass extinction, and the succeeding marine ecosystem recovery, recording a sequence of environmental and biotic events. In South China, there exist numerous well-preserved and continuous Devonian-Carboniferous boundary successions that were formed in low-latitude passive margin basin, and this presents a unique opportunity to decipher the strata along a proximal to basinal transect using integrated biostratigraphical, event-stratigraphical, and geochemical approaches. Our geochemical data (δ 13 C carb , δ 15 N bulk , δ 238 U and Mo/U enrichments, I/Ca ratio) indicated local and global C-N cycling perturbations and marine anoxia in the main phase of the Hangenberg Crisis interval (Middle Siphonodella praesulcata Zone), which coincided with a major regression in South China. Stromatoporoid biostromes and most typical Devonian faunas did not survive into the interval, and the deep-water black shales yield only opportunistic survivors, such as ammonoid Postclymenia cf. evoluta and bivalve Guerichina, along with miospores belonging to the LN Zone. The upper Hangenberg Crisis interval (Upper Si. praesulcata Zone, equal to the Protognathodus kockeli Zone) is marked by initial post-glacial transgression, a global δ 13 C carb spike, and opportunistic faunal blooms, coincident with conodont biofacies shift to the polygnathid-protognathodid biofacies. The Protognathodus fauna, nearly absent from platform facies, is often found in the condensed upper crisis interval of the basin, slope, and platform margin facies within the Youjiang Basin, although the abundance is extremely low and the phylogenetic lineage of Pr. meischneri-Pr. collinsoni-Pr. kockeli cannot be recognised in most successions. In South China, the first occurrence of Pr. kockeli seems to correspond to lithofacies changes, recorded in the first level of transgression just above the Hangenberg Sandstone event. Multiple lines of evidence, including great spatial heterogeneity of δ 13 C carb and δ 15 N bulk records, extremes of redox proxies, and lack of macrofossils, suggest that marine habitats remained in a critical/turbulent state during the Upper Si. praesulcata Zone, triggering the opportunistic blooms and minor extinctions. Following the crisis intervals, radiation/ recovery of many fossil groups did not occur until the upper part of the Siphonodella sulcata Zone to the Si. duplicata Zone. In particular, a negative shift of δ 13 C carb to pre-crisis values occurring near the base of the Si. sulcata/Pr. kuehni Zone could be recognised worldwide. The research history, current status, and achievement of Devonian-Carboniferous boundary in China are briefly reviewed.

During the Devonian period, major continents/blocks were located in the southern hemisphere (e.g. Stampfli et al. 2002, 2013; Scotese 2014), with a major mountain range running on the northeastern margin of Laurussia to Gondwana: the Appalachian range (Fig. 1) (DeSantis 2010, Scotese 2014). This period of time is marked by one of the most significant modifications in palaeobiogeography with the precipitated end of the strong faunal endemism of the Emsian-Eifelian and the initiation of the Givetian-Frasnian cosmopolitanism (Oliver & Pedder 1979b). During the early Emsian to late Eifelian interval, three distinct faunal assemblages allow the definition of three different marine realms (Oliver & Pedder 1979a, 1979b, 1994; May 1995, 1997b), separated by various barriers. The Malvinokaffric Realm (MKR), located along the margins of Gondwana (Fig. 1), is relatively poor in corals and it is characterized by cold-water species (Oliver 1990;

“…It is one of the hotspots for the study of the Devonian system (Carmichael et al, 2019). After the Wuyi-Yunkai intraplate orogeny (Li et al, 2010;Zhang et al, 2016), the Early Devonian (Pragian Stage) transgression followed by the Late Devonian regression gives birth to numerous well-preserved Devonian sections (Figure 1B) and provides ideal sedimentary and PaleoBios records (Ma et al, 2016;Qie et al, 2019) for global comparisons (Klapper et al, 1993). The eustatic fall and the mass extinction of the deeper-water brachiopods and conodonts and shallow-water coral and ostracods occurred correlative with the latest Frasnian Pa. linguiformis Zone to the Famennian Lower Pa. triangularis Zone (Ma et al, 2016).…”

Mercury Anomalies Link to Extensive Volcanism Across the Late Devonian Frasnian–Famennian Boundary in South China

The Late Devonian Frasnian–Famennian (F–F) mass extinction has been long-time debated by non-volcanic causes, extra-terrestrial impacts, and large igneous province (LIP) eruptions. To better understand the ultimate cause of the F–F mass extinction, here we investigate the chemostratigraphy of mercury (Hg) and total organic carbon (TOC) on two marine F–F strata in the Dushan area, South China. In both sections, high Hg and Hg/TOC anomalies were observed near the F–F boundary. These anomalies are in line with those recently observed in Morocco, Germany, Poland, and north Russia, suggesting a global Hg flux. The Late Devonian LIP eruptions, which are believed to have emitted massive amounts of Hg, could be responsible for the global Hg and Hg/TOC anomalies around the F–F boundary. The observed Hg and Hg/TOC anomalies coincide with the extinction of Frasnian fauna in the Dushan area, implying a causal link between the Viluy, Kola, and Pripyat-Dnieper-Donets LIP eruptions and the F–F mass extinction.
