“…%) found in marine pyrite from the late Archean ocean and the apparent Ni enrichment observed in the core of some of these Geochemical Perspectives Letters Letter pyrite grains (Large et al, 2017). Furthermore, it could be inferred that rapid precipitation of Ni-rich pyrite in euxinic basins of the late Archean ocean (Reinhard et al, 2009;Large et al, 2017) would be expected to have drastically lowered the Ni/Fe ratio of the ocean, as observed by Konhauser et al (2009) in BIFs, which could have contributed to trigger the GOE, as proposed by the latter authors.…”

“…Isotopic compositions of iron and sulphur in pyrites from sedimentary rocks have been proposed as potential proxies to assess the redox state of ancient oceans (Rouxel et al, 2005;Reinhard et al, 2009;Marin-Carbonne et al, 2014), the oxygen outgrowth in the atmosphere (Catling and Claire, 2005;Ohmoto et al, 2006) and early microbial metabolisms (Johnson et al, 2008). Moreover, trace metals incorporated in pyrite have been recognised as proxies for ancient ocean chemistry (Large et al, 2017). Besides, the formation of pyrite from a (Fe,Ni)S precursor has been proposed to be involved in the 'Fe-S World' theory of the origin of life Wächtershäuser, 1997, 1998).…”

“…In parallel, nickel has been recognised as an essential biocatalytic metal agent in iron-sulphur enzymes, especially acetyl-CoA synthase, which is a major enzyme of acetogenic bacteria and methanogens for fixing CO/CO 2 (Darnaud et al, 2003). Lastly, nickel has a particular ability to be incorporated in pyrite during early diagenesis of marine and coastal sediments (Huerta-Diaz and Morse, 1992;Morse and Luther, 1999;Large et al, 2017), which largely contributes to Ni immobilisation in mangroves (Noël et al, 2014(Noël et al, , 2015. The image that arises is one in which pyrite is a regulator of iron and trace metal distribution in modern and ancient environments.…”

Chemical and isotopic compositions of pyrites are used as biogeochemical tracers in Archean to modern sediments. Moreover, pyrite formation from monosulphide precursors has been proposed to be involved in prebiotic chemistry. However, the factors controlling pyrite formation and distribution in the sedimentary record are incompletely understood. Here, we show that Ni 2+ ions accelerate ~5 times the nucleation of pyrite at ambient temperature. Using Fe and Ni K-edge EXAFS and TEM-EDXS we demonstrate that Ni(II) is directly involved in the nucleation of pyrite synthesised by reacting Fe(III) with Na 2 S in the presence of aqueous Ni(II) impurity. Initial formation of a Ni-enriched pyrite core is followed by overgrowth of a Ni-depleted pyrite shell, leading to compositional zoning of the Fe 1-x Ni x S 2 nanocrystals (x = 0.05 to 0.0004). The molar Ni/Fe ratio in the final aqueous solution was then 2000 times lower than the starting ratio of 0.01. This enhanced and accelerated trapping of Ni by pyrite could be of prime importance in controlling Ni concentration in the ocean during early diagenesis of marine sediments, and could thus have important implications for interpreting abundances of Ni and pyrite in the sedimentary record. In addition, acceleration of pyrite nucleation in the presence of nickel could help understanding the role of Fe-Ni sulphides in catalysing potential prebiotic reactions.

“…Fluctuations in the trace element abundances of deep marine black shales have been used to infer variations in atmospheric oxygenation levels through time (Chen et al., ; Johnson et al., ; Large et al., ; Pogge von Strandmann et al., ; Reinhard et al., ; Stüeken et al., ). A significant increase in selenium abundance within sedimentary pyrite globally has been identified from 580 to 470 Ma (Large et al., ).…”

Tellurium, selenium and cobalt enrichment in Neoproterozoic black shales, Gwna Group, UK: Deep marine trace element enrichment during the Second Great Oxygenation Event

et al. 2018

Black shales of the late Neoproterozoic Gwna Group (570-580 Ma), UK, contain enrichments of tellurium (Te), selenium (Se) and cobalt (Co) relative to average shale compositions. The Te and Co enrichments bear comparison with those of ferromanganese crusts in the modern deep ocean. Gwna Group deposition coincides with the Second Great Oxidation Event, which had a significant effect on trace element fixation globally. Selenium and Te concentrations within these black shales indicate increased continental weathering rates, high biological productivity and corresponding increases in atmospheric O 2 concentrations. Cobalt, nickel (Ni) and arsenic (As) enrichments in this succession are secondary mineralisation phases. Demand for many of the trace elements found enriched in the Gwna Group black shales make their mechanisms of accumulation, and variations through the geological record, important to understand, and suggests that new resources may be sought based on black shale protoliths from this period.

“…Our results show that the pyrite grains from the intrusions, aureole and cokeite differ in trace element contents (those of the pyrite from unaffected coal were mostly below the detection limits). It is suggested that high Co/Ni ratios (>1) and high Se contents (>50 ppm) may reflect the hydrothermal genesis of pyrite [60][61][62][63]. In our work, the Co/Ni ratio in Py III was >1 (Figure 5a) and the Se contents were 72.37-989.27 ppm (Figure 5b), indicating that Py III may have been crystallized from magmatic-hydrothermal fluids [60][61][62][63].…”

Source and Enrichment of Toxic Elements in Coal Seams around Mafic Intrusions: Constraints from Pyrites in the Yuandian Coal Mine in Anhui, Eastern China

Pyrite, a mineral that can cause potential environmental issues in coal mining, is commonly found in coal seams around intrusions. In this paper, pyrites from the Yuandian Coal Mine (Huaibei Coalfield, Anhui, Eastern China) were studied using SEM, Raman and LA-ICP-MS. The pyrite morphologic and geochemical data suggest that (1) four pyrite generations are present (framboidal sedimentary pyrites (Py I) in the original coal, coarse-grained magmatic pyrites (Py II) in the intruding diabase, fine-grained metamorphic pyrites (Py III) in the intrusive contact aureole, and spheroid/vein hydrothermal pyrites (Py IV) in the cokeite); and (2) concentrations of cobalt, nickel, arsenic, selenium, lead and copper in the metamorphic pyrites are much higher than the other pyrite generations. We propose that mafic magmatism is the main contributor of the toxic elements to the intrusion-related cokeite at Yuandian.
