“…Consequently, a conservative overall uncertainty (2SD, the expanded combined uncertainty with a coverage factor of 2) of AE0.032& or AE0.016& per amu (eqn (VI)) is adopted for all d 60/58 Ni measurements presented in this study unless stated otherwise. Notably, the level of precision associated with the method presented here is similar to those achieved in previous studies (AE0.018& to AE0.089&, 2SD 6,16,27,39,40,[43][44][45][64][65][66][67][68] ).…”

“…Therefore, the Re concentration and TOC are correlated in reduced sediments. Many previous studies have documented that both Re and Mo, and PGE as well, are mainly stored in pyrite in organic-rich sediments (Brumsack, 2006;Colodner, 1991;Gadd et al, 2019;Pašava et al, 2019;Rosenthal et al, 1995;Sundby et al, 2004;Wanty and Goldhaber, 1992;Zheng et al, 2000). For example, Gadd et al (2019) analyzed sulfide minerals in reduced sediments and the bulk sediments, using LA-ICP-MS, and found that the Re concentration in pyrite is as high as 500 ppm.…”

“…The differences in their affinity with organic matter explains how Mo and Ni are precipitated in organicrich black shale, but does not provide any information on their sources. In addition, some researchers believe that Ni can come from the weathering of mafic rocks, based on the isotopic composition of Ni (Pašava et al, 2019). In contrast, V has a high concentration in the seawater of the early Cambrian ocean and its accumulation in the black shale could occur by way of adsorption to clay minerals (Lu et al, 2021).…”

A polymetallic layer is usually developed at the bottom of the Early Cambrian black shale in Guizhou province. The mineral that makes up the polymetallic layer is related to the sedimentary facies. To analyze the differentiation mechanism between polymetallic deposits (Ni‐Mo and V), the Zhijin Gezhongwu profile located in the outer shelf and the Sansui Haishan V deposit located in the lower slope are selected to study the in‐situ sulfur isotope and trace elements of pyrite. The results show that δ34S values of pyrite vary widely from −7.8 ‰ to 28 ‰ in the Gezhongwu profile, while the δ34S values are relatively uniform (from 27.8 ‰ to 38.4 ‰) in the Haishan profile. The isotopic S composition is consistent with the transition that occurs in the sedimentary phase from the shelf to the deep sea on the transgressive Yangtze platform; this indicates that the δ34 values in seawater must be differently distributed in depositional environments. The sulfur in the Ni‐Mo layer is produced after the mixing of seawater and hydrothermal fluid, while the V layer mainly originates from seawater. Overall, the Ni‐Mo and V deposits have been differentiated mainly on the basis of the combined effect of continental weathering and hydrothermal fluid.
