A detrital model for the origin of gold and sulfides in the Witwatersrand basin based on Re-Os isotopes

Multiple sulphur and iron isotope composition of detrital pyrite in Archaean sedimentary rocks: A new tool for provenance analysis

“…Barnicoat et al, 1997). Our data add to the long list of arguments in favour of a detrital origin for rounded pyrite, such as the presence of abrasion features, sedimentological control on pyrite distribution, geochemical heterogeneity, and UPb and Re-Os ages greater than the depositional age (Ramdohr, 1958;Saager, 1970;Hallbauer, 1986;Barton and Hallbauer, 1996;Kirk et al, 2001;England et al, 2002;Minter, 2006). (Canfield et al, 2000), while a larger range of δ 34 S values in sedimentary sulphides is generally attributed to bacterial sulphate reduction in localized sulphate-rich environments (e.g.…”

Re-assessing the surface cycling of molybdenum and rhenium

“…Data for MoS 2 are from Noddack and Noddack (1931), Fleischer (1959, 1960, Morachevskii and Nechaeva (1960), Terada et al (1971), McCandless et al (1993, Markey et al (1998), Stein et al (1998Stein et al ( , 2001, Selby and Creaser (2001), Barra et al (2003), Mao et al (2003), Sun et al (2003b), Berzina et al (2005), Zhang et al (2005), Mao et al (2006), and Selby et al (2007b). Data for 'FeS 2 ' are from Freydier et al (1997), Brü gmann et al (1998, Cohen et al (1999), Mathur et al (1999Mathur et al ( , 2000Mathur et al ( , 2005, Stein et al (2000), Arne et al (2001), Kirk et al (2001Kirk et al ( , 2002, Barra et al (2003), Hannah et al (2004), Morelli et al (2004Morelli et al ( , 2005Morelli et al ( , 2007, Zhang et al (2005), and Liu et al (2008). and Re indicates that a significant proportion of Re, but not Mo, is organically-bound, perhaps as metalloporphyrin species (Miller, 2004).…”

In-situ LA-ICP-MS trace elemental analyses of magnetite and Re–Os dating of pyrite: The Tianhu hydrothermally remobilized sedimentary Fe deposit, NW China

“…It has been documented that Re-Os isotopic systematic of pyrite (sometimes Cu-sulfides) is robust for dating sedimentary mineralization system and can remain unaffected by greenschist-facies metamorphism (e.g. Huang et al, 2013b;Kirk et al, 2001;Selby et al, 2009). The initial 187 Os/ 188 Os ratios obtained from isochron diagrams can be used to infer the source of Os and by inference the other ore-forming metals (Mathur et al, 2000(Mathur et al, , 2002Morgan et al, 2000).…”
