“…Keith et al (2014) found a linear correlation between the sphalerite Fe/Zn ratio and fluid temperature, which can be expressed by the equation (Fe/Zn) Sph = 0.0013(T) − 0.2953, this method permitting the estimation of some massive sulfide deposits (VHMS). Frenzel et al (2016) reviewed previous research methods and re-established a homogenization temperature calculation method based on Ga, Ge, Fe, Mn and In elements, which was verified as being able to calculate homogenization temperatures within the margins of error (Yu et al, 2020;Wei et al, 2021) but also has some limitations (Horn et al, 2019).…”

“…The fractionation of trace elements in sphalerite is known to be influenced by many factors, such as the crystallization temperature, source of metals, as well as the cooling history of the ore-forming fluids (Cook et al, 2009). Therefore, the mineral chemistry of sphalerite is another approach to detect the physicochemical conditions of the ore-forming process for ore deposits (Kelley et al, 2004;Gagnevin et al, 2014;Horn et al, 2019;Sheng et al, 2019;Zhuang et al, 2019;Yu et al, 2020). Möller (1987) established a relationship between the sphalerite Ga/Ge ratio and fluid inclusion homogenization temperature, this method being used to constrain the deposit formation temperature (Mladenova and Valchev, 1998;Navarro-Ciurana et al, 2017).…”

The Sinongduo mining region includes two types of mineralizations: the epithermal and the carbonate‐hosted Pb‐Zn‐Ag deposits. Despite being studied for many years, the ore formation process and genesis of the carbonate‐hosted Pb‐Zn‐Ag deposits remain poorly understood. The Pb‐Zn‐Ag ore bodies occur as veins and are hosted by limestone and dolostone of the Permian Xiala Formation. Three sulfide mineralization substages have been identified at the Sinongduo carbonate‐hosted deposit. Indium coupled with Cu, Co and Sn was incorporated into sphalerite as substitutions: 2Zn2+ ↔ Cu+ + In3+, (3n/2 + 1)Zn2+ ↔ Co2+ + nIn3+ or (2n + 1)Zn2+ ↔ Co2+ + n(Cu+ + In3+) (n > 1) and 4Zn2+ ↔ Sn2+ + 2In3+. Sphalerite and pyrite in the mineralization stage display δ34S values in a narrow range of +5.7‰ to +11.3‰, which are similar to those of Palaeocene igneous rocks, indicative of a magmatic source of sulfur. We present systematic carbon‐hydrogen‐oxygen isotope results that further support a magmatic source for the ore‐forming fluids that were influenced by meteoric water. Furthermore, the Pb isotope compositions of sulfide minerals in the Sinongduo carbonate‐hosted deposit overlap with the values of coeval Linzizong volcanic rocks and are similar to those of Indian Ocean sediments, indicating upper crustal sources of metals. We conclude that the Sinongduo carbonate‐hosted Pb‐Zn‐Ag deposit is a medium‐ to low‐temperature magmatic‐hydrothermal deposit related to Linzizong magmatism.

“…Furthermore, Figure 11 summarizes the trace elemental compositions of galena from different genetic types of deposits (skarn, SEDEX, epithermal, and MVT). Elemental Bi is generally associated with high-temperature ore-forming fluids, whereas elemental Sb is more mobile in low-temperature ore-forming fluids [61,62]. The galena from skarn deposits, which are characterized by high-temperature fluids, is distinctly enriched in Bi while depleted in Sb.…”

The Caoziwa Pb–Zn deposit is one of the typical vein-type Pb–Zn deposits in the western part of the Tengchong block. Due to limited research, the genesis of these deposits is unknown. In this study, the sulfur isotopic and trace elemental compositions of sulfides from the Caoziwa Pb–Zn deposit were analyzed to trace the sources of ore-forming materials, and to reveal the genetic type of this deposit. The results show that abundant Co, Ni, As, and Se, and less Cu, Zn, Ag, Cd, Sn, Sb, Te, Pb, and Bi could enter pyrite by isomorphic substitution. Elemental Mn, Fe, Cd, Co, and Ni could substitute Zn to enter sphalerite, while the contents of Ag, Sn, and Sb are mainly controlled by the Pb-rich inclusions in sphalerite. Elemental Bi, Sb, Cd, Sn, Ag, and Tl mainly enter the galena grains via an isomorphic substitution mechanism of (Bi, Sb)3+ + (Cd, Sn)2+ + (Ag, Tl)+ ↔ 2Pb2+. Both sulfur isotopic compositions and trace elemental compositions indicate that the ore-forming materials and fluids of the Caoziwa Pb–Zn deposit mainly originate from magmatic hydrothermal fluid related to Paleocene granitic magmatism. Combined with the geological facts that some skarnizations developed in the northern part of the ore field near the Paleocene granite, the Caoziwa Pb–Zn deposit is suggested to be a magmatic hydrothermal vein-type deposit that probably belongs to a distal part of a skarn mineralization system developed by the intrusion of Paleocene granitic magmatism in the western part of the Tengchong block.

“…The highest and lowest valence states of Mn oxides observed in Nature are IV and II, respectively (Owen and Bricker, 1965). Manganese deposits were produced mainly in the Precambrian such as Moanda, Gabon (Gauthier-Lafaye et al , 1996) and Hunan Province, South China (Yu et al , 2020), while high-quality Mn oxide ores were enriched in the Ordovician, Carboniferous and Quaternary such as at Molango, Mexico (Martino, 1986). Manganese ore is generally formed during deep sea sedimentation, where the main ore is manganese carbonates such as rhodochrosite (Roy, 2006).…”

Manganese (Mn) oxides have been prevalent on Earth since before the Great Oxidation Event and the Mn cycle is one of the most important biogeochemical processes on the Earth's surface. In sunlit natural environments, the photochemistry of Mn oxides has been discovered to enable solar energy harvesting and conversion in both geological and biological systems. One of the most widespread Mn oxides is birnessite, which is a semiconducting layered mineral that actively drives Mn photochemical cycling in Nature. The oxygen-evolving centre in biological photosystem II (PSII) is also a Mn-cluster of Mn4CaO5, which transforms into a birnessite-like structure during the photocatalytic oxygen evolution process. This phenomenon draws the potential parallel of Mn-functioned photoreactions between the organic and inorganic world. The Mn photoredox cycling involves both the photo-oxidation of Mn(II) and the photoreductive dissolution of Mn(IV/III) oxides. In Nature, the occurrence of Mn(IV/III) photoreduction is usually accompanied with the oxidative degradation of natural organics. For Mn(II) oxidation into Mn oxides, mechanisms of biological catalysis mediated by microorganisms (such as Pseudomonas putida and Bacillus species) and abiotic photoreactions by semiconducting minerals or reactive oxygen species have both been proposed. In particular, anaerobic Mn(II) photo-oxidation processes have been demonstrated experimentally, which shed light on Mn oxide emergence before atmospheric oxygenation on Earth. This review provides a comprehensive and up-to-date elaboration of Mn oxide photoredox cycling in Nature, and gives brand-new insight into the photochemical properties of semiconducting Mn oxides widespread on the Earth's surface.
