“…Opinions differ regarding the age of the Hongguleleng Formation. Previous studies have exhibited that the age of the Hongguleleng Formation was ranging from the Famennian to the early Carboniferous (Zhao, 1986;Zhao and Wang, 1990;Xia, 1996), while several authors believed that there were at least upper Frasnian strata at the bottom of the Hongguleleng Formation (Xia, 1997;Chen et al, 2009;Suttner et al, 2014;Wang et al, 2016).…”

“…The Hongguleleng Formation of the Bulongguoer section in Western Junggar, NW Xinjiang, China, has attracted much attention due to its well-exposed Upper Devonian lithological units and abundant fossils, such as conodonts (Zhao, 1986;Xia, 1996;Wang et al, 2016), brachiopods (Ma et al, 2011), rugose corals (Liao and Cai, 1987), ammonoids (Zong et al, 2015), trace fossils (Fan and Gong, 2016), and ostracods (Song et al, 2017b). Multiple geochemical proxies, as well as lithological and facies analyses have also been discussed around the Devonian-Carboniferous (D/C) and Frasnian-Famennian (F/F) boundaries in the Bulongguoer section (e.g.…”

Nevertheless, there is still no unanimous agreement on the chronostratigraphic framework for the Hongguleleng Formation, and the debate about the position of the F/F boundary in Western Junggar is still ongoing.…”

Palynological investigations have been carried out on samples from the Upper Devonian Hongguleleng Formation of Western Junggar, Xinjiang, NW China. In total, 28 miospore species belonging to 19 genera and 28 acritarch species assigned to 17 genera have been recognized from the Lower member of the Hongguleleng Formation in the Bulongguoer section. The palynofloral assemblages, in particular the miospore taxa, are similar to those from the eastern European early Famennian Cyrtospora cristifer -Diaphanospora zadonica (CZ) miospore Biozone, albeit quantitatively and qualitatively depauperate. The miospore assemblage zone is also consistent with the previous zonal schemes in light of brachiopod and conodont fauna assemblages, as well as carbon isotope geochemistry, that indicates a correspondence to the Palmatolepis crepida conodont Biozone. The earliest Famennian Corbulispora vimineus -Geminospora vasjamica (VV) (more or less equivalent to the Palmatolepis triangularis conodont Biozone) miospore Biozone is most likely to be missing in the Hongguleleng Formation of the Bulongguoer section . The palynostratigraphy and sedimentary sequence in Western Junggar are very similar to those from some other regions of South China, western and eastern Europe, which increases the knowledge of the evolution of the palaeoclimate, palaeogeography and regional sedimentary environment of the Central Asian Orogenic Belt (CAOB), Eastern European Platform, and Laurussia.

“…The western Junggar was located in a volcanic arc setting during the middle Palaeozoic (Xiao, Huang, Han, Sun, & Li, ), with widespread Palaeozoic sedimentary rocks and various types of volcanic rocks (Figure ). The Late Devonian Hongguleleng Formation now cropping out in the Shaerbuerti Mountains was deposited in the back‐arc basin of the Zharma–Saur arc (Figure ), which yield abundant and diversified faunas and floras (e.g., brachiopods, bryozoans, conodonts, trilobites, and plants; Chen et al, ; Suttner et al, ; Wang et al, ; Windley et al, ; Xia, ; Xu, Cai, Liao, & Lu, ; Zong, Fan, & Gong, ) as well as trace fossils (Fan & Gong, ).…”

Late Devonian benthic ostracods from western Junggar, NW China: Implications for palaeoenvironmental reconstruction

2018

View full text Add to dashboard Cite

This study focuses on the palaeoecology of the Late Devonian ostracods based on more than 4,500 carapaces and valves collected from stratal sections in western Junggar, NW China.According to the ostracod faunas from the Hongguleleng Formation, 3 ecological assemblages are proposed for open oceanic island arc context, that is, Ostracod Assemblage-1, Ostracod Assemblage-2, and Ostracod Assemblage-3. They characterize the foreshore, nearshore, and offshore environments, respectively. The water energy should be the first environmental factor controlling the composition of the ostracod assemblages from the Lower Member of the Hongguleleng Formation, and salinity fluctuations could be also involved.

The Upper Devonian of western Junggar, Xinjiang, northwestern China bears abundant marine fossils and has attracted much attention with respect to palaeontological and stratigraphical studies. However, the records of ammonoids are sparse and the previously established assemblages need to be supplemented or emended through further collections. Here, we describe the Gonioclymenia fauna from the Wulan Member of the Hongguleleng Formation based on thorough and systematic sampling, including Gonioclymenia junggarensis n. sp., a member of the Gonioclymenia subcarinata Group, an evolute clymeniid, Cymaclymenia sp., and an indeterminate species of the Sporadoceratidae or Prionoceratidae. The strata bearing the Gonioclymenia fauna in western Junggar can be correlated with the upper Famennian UD V-A 2 to V-C of the Clymenia Ammonoid 'Stufe', approximately corresponding to the Bispathodus aculeatus aculeatus Conodont Zone (former Middle expansa Zone). The Gonioclymenia species from western Junggar indicate close relationships with Europe and North Africa, while the latter two regions show a higher abundance and species diversity within the genus. New specimens described here enrich the composition of the Gonioclymenia fauna of western Junggar, and shed lights on the stratigraphic correlation and subdivision of the Upper Devonian in this region at a fine resolution.
