“…Likewise, no independent comparison of the results of Bente and Nielsen (1982) for bismuthinite-sulfur fractionations can be made, but their results are also consistent with theoretical predictions. Expressions for sulfur isotope fractionation of argentite, digenite, covellite, and bismuthinite with H 2 S, based on the experimental results of Hubberten (1980) and Bente and Nielsen (1982) combined with the sulfur-H 2 S fractionations from Ohmoto and Rye (1979) are presented in Table 1.…”

“…Hubberten (1980) conducted synthesis experiments investigating sulfur isotope fractionations between 280 and 700 °C for galena, argentite (Ag 2 S), covellite (CuS) or digenite (Cu 9 S 5 ) equilibrated with sulfur. Bente and Nielsen (1982) conducted reversed experiments between 150 and 600 °C on isotopic fractionations between bismuthinite (Bi 2 S 3 ) and sulfur. Suvorova and Tenishev (1976) and Suvorova (1978) conducted synthesis experiments investigating sulfur isotope fractionation between 300 and 600 °C between various mineral pairs including sphalerite-molybdenite (Sl-Mb), galena-molybdenite (GnMb), galena-herzenbergite (SnS)(Gn-Hz), tungstenite (WS 2 )-molybdenite (Tn-Mb), and stibnite-molybdenite (St-Mb).…”

“…So far, the experimental research, which aims at sulfur isotope fractionations in sulfides, has focused on a few minerals, such as ZnS, PbS, FeS 2 , CuFeS 2 , CuS, CuS 2 , AgS, and Bi 2 S 3 (Grootenboer and Schwarcz 1969;Kajiwara et al 1969;Rye and Czamanske 1969;Czamanske and Rye 1974;Kajiwara and Krouse 1971;Salomons 1971;Kiyosu 1973;Smith et al 1977;Hubberten 1980;Bente and Nielsen 1982). And the theoretical calculations of sulfur isotope fractionation are also few.…”

The sulfides are an important group of minerals. As a geochemical tracer, the sulfur isotope fractionation in sulfides can be used to analyze the ore-forming process and the ore-forming material source. Fe, Co, Ni, and Mn are the first row transition metals, and pyrite (FeS 2 ), cattierite (CoS 2 ), vaesite (NiS 2 ), and hauerite (MnS 2 ) crystallize in the pyrite-type structure. However, there are few studies on the sulfur isotope fractionation in these disulfides. So studying the isotope fractionation between them provides the opportunity to examine the various members of a structural group in which only the metal atom is changed, thereby providing information that permits a systematic development of concepts regarding sulfur isotope fractionation in transition-metal disulfides. In the present paper, the sulfur isotope fractionation parameters for pyrite, cattierite, vaesite, and hauerite with the pyrite-type structure have been calculated using first-principles methods based on density functional theory in the temperature range of 0-1000 °C. The structure parameters of these four minerals and the vibration frequencies of pyrite are in good agreement with previous experimental values. The metal-sulfur distance increases in the order FeS 2 , CoS 2 , NiS 2 , and MnS 2 , the sulfur-sulfur distance decreases in the order FeS 2 , CoS 2 , MnS 2 , and NiS 2 , these two sequences agree with the experimental results. Our calculations show that the order of heavy isotope enrichment is pyrite > cattierite > vaesite > hauerite. It seems that the sulfur isotope fractionation in disulfides depends mainly on the metal-sulfur bonds.
