“…6), i.e., Shuyu and Meishanaspis from the lower part of the Tangchiawu Formation in Northwest Zhejiang (Gai et al, 2005(Gai et al, , 2011Shan et al, 2022a), Qingshuiaspis and Jiangxialepis from the Qingshui Formation in Northwest Jiangxi (Shan et al, 2022a). Hanyangaspis and Hongshanaspis are comparable to Latirostraspis from the Houjiatang Formation in East Anhui (Wang et al, 1980), Konoceraspis from the Rongxi Formation in Northwest Hunan (Pan, 1992), and Kalpinolepis and Nanjiangaspis from the Tataertag Formation in Tarim region (Wang et al, 1996(Wang et al, , 2002, all of which belong to the Hanyangaspidae. Sinacanthus and Neosincanthus are established mainly based on the remains of fin spines of chondrichthyans, and are known exclusively from the LRBs in Yangtze and Tarim regions.…”

A new species of Shuyuidae (Eugaleaspiformes, Galeaspida), Jiangxialepis jiujiangensis sp. nov., is described from the lower Telychian (Llandovery, Silurian) Qingshui Formation in Jiujiang, Jiangxi Province, China. The new species differs from the type species J. retrospina from Wuhan, Hubei Province in its sharp and posteriorly positioned median dorsal spine and narrow spine‐shaped inner cornual processes. The Silurian strata in Xiushui–Wuning area has provided a standard framework for the correlation of Silurian shallow marine red beds in South China. Thus, the finding of J. jiujiangensis from the Silurian Lower Red Beds (LRBs) in Jiangxi Province bears very important biostratigraphic significance. It can directly compare to Jiangxialepis retrospina from the Fentou Formation in Wuhan, Hubei Province in the genus level. This indicates that the age of the fish‐bearing strata in Wuhan is most likely to be the early Telychian rather than middle Telychian as previously assumed.

“…Cementation was the main cause of reservoir deterioration (Shi et al, 2020). The high-energy facies are commonly exposed at the low sea level and go through dissolution and leaching, therefore, become favorable reservoirs in the high-frequency cycles (Wang et al, 2022). The high-energy facies with late dissolution diagenesis are the favorable reservoir facies belts for exploration.…”

Shallow-water carbonates from the Yingshan Formation are important target of hydrocarbon exploration in Tarim Basin. Detailed descriptions of outcrop, core, and thin sections, isotopic composition analysis, and trace element analysis were conducted. Seven lithofacies which consists of two facies belt groups were identified and used to interpret deposition environments of Yingshan Formation: (1) peritidal carbonate, with relatively lower δ13C values from −4.2% to −1.9%, mainly represented by intertidal to supratidal facies and restricted subtidal facies and (2) open-marine subtidal carbonate, with higher δ13C values (−1.5% to −0.3%), mainly consists of shoal facies and interbank sea facies. On the basis of the lithology sets, four types of meter-scale cycle model (types A–D) were grouped into peritidal sequences and subtidal sequences. On the basis of vertical lithofacies, cycle stacking patterns, and accommodation variations in Fischer plots, two third-order depositional sequences (SQ1–SQ2) were recognized. The sequence boundary between SQ1 and SQ2 is not only a surface of a positive shift of δ13C values, but also the transitional zone of cycle stacking patterns. The sequences can be further divided into four fourth-order sequence sets: Sq1–Sq4. The lower sequences (Sq1–Sq2) are dominated by peritidal facies and characterized by a progressive decreasing in accommodation space probably indicates a longer-term fall in sea level. The upper sequences (Sq3–Sq4) are mainly dominated by subtidal facies and characterized by the accommodation space with a progressive increasement, likely indicates a rising sea level with a longer term. The facies-controlled reservoirs are mainly present in the Sq3, related to the sequence boundary between SQ1 and SQ2.

“…1a, c). The Silurian strata in the northwestern margin of Tarim Basin are subdivided into four formations in ascending order: the Kalpintag, Tataertag, Ymogantau, and Kezirtag formations (Wang et al, 1996(Wang et al, , 2002Zhao et al, 2009). Being conformably in contact with the underlying Kalpintag Formation and the overlying Ymogantau Formation, the fish-bearing Tataertag Formation mainly consists of gray, grayish-white siltstone, sandstone, and mudstone with abundant invertebrate fossils such as brachiopods, gastropods, bivalves, and chondrichthyans microfossils distributed throughout the sequence (Li et al, 1997).…”

New discovery of the early Silurian fossil fish Changxingaspis (Xiushuiaspidae, Galeaspida), Changxingaspis nianzhongi sp. nov. and C. gui, are described from the Tataertag Formation in Tarim Basin and the Kangshan Formation in Zhejiang Province, respectively. C. nianzhongi mainly differs from C. gui in the shape of the median dorsal opening that is transverse elliptic with a width/length ratio of about 3.0, the long lateral transverse canals extending to the lateral margin of the headshield, and the second lateral transverse canal with dichotomous branchings. Discovery of new specimens of C. nianzhongi from the Tataertag Formation and C. gui from the Kangshan Formation provide direct evidence on the genus level for the correlation between these two formations, which further supports the Silurian fish‐bearing red beds in northwest Zhejiang belonging to the Silurian Lower Red Beds (LRBs) rather than the Upper Red Beds (URBs). Additionally, as the first record of the Changxingaspis in Tarim Basin, this new discovery extends the paleogeographical distribution of this genus from the South China Block to the Tarim Block, providing new evidence to support faunal exchanges between these two blocks and the hypothesis of a united Tarim–South China Block during the early Silurian.
