Section: Pge Variations In Cadia Ore Veins: Implications For Pge Mobimentioning

“…The solubility of PGE in saline solutions is several orders of magnitude lower than that of Au, Cu, Ni and Fe (Simon and Pettke, 2009;Tagirov et al, 2013;Park et al, 2016). The solubility of Pd in brine is ~1 ng/g (Tagirov et al, 2013), whereas that of Au is 0.3-0.8 μg/g and Cu is 0.3-0.8 wt.% (Ulrich et al, 1999). Despite this, several porphyry Au-Cu deposits are known to host significant amounts of PGE although not at economic concentrations (e.g., Eliopoulos and Economou-Eliopoulos, 1991;Tarkian and Koopmann, 1995;Tarkian and Stribrny, 1999).…”

“…Although there is considerable overlap with the slop16.dat update for SUPCRT92 (Shock, 2016), OBIGT uses different data sources for aqueous Al species (Tagirov and Schott, 2001), As species (Nordstrom and Archer, 2003), Au, Ag, and Cu species Zotov, 2001, 2010), Pd species (Tagirov et al, 2013), Zn species (Akinfiev and Tagirov, 2014), and Pt species (Tagirov et al, 2015). Other notable differences are the inclusion of goethite, other Fe-oxyhydroxides, and evaporite minerals (Majzlan et al, 2003;Grevel and Majzlan, 2009), aqueous phenanthrene and methylphenanthrene isomers , experimentally derived HKF parameters for aqueous adenine (Lowe et al, 2017), and all of the organic compounds reported by Helgeson et al (1998) and Richard and Helgeson (1998).…”

Thermodynamic calculations are an essential tool for many areas of geochemistry. Thermodynamics provides a framework for the quantitative description and prediction of the solubilities and relative stabilities of different minerals, metal transport in hydrothermal fluids, and geobiochemical reactions that drive microbial metabolism and contribute to the compositional variation of proteins. Accessible and up-to-date software and databases are important for the development and reproducible application of thermodynamic models. CHNOSZ is a free package for R that has been frequently updated since its first release in 2008. The package provides an integrated set of functions to calculate the standard molal thermodynamic properties and chemical affinities of reactions. It uses the graphical capabilities of R to produce high-quality chemical activity diagrams for aqueous species and predominance diagrams including Eh-pH (Pourbaix) and logf O 2-T diagrams. The extensive database utilizes the well-known revised Helgeson-Kirkham-Flowers (HKF) equations for aqueous species. Recent additions to the database include the Berman equations for minerals, the Deep Earth Water model, which extends the applicability of the HKF equations to higher pressures, and the Akinfiev-Diamond model for aqueous nonelectrolytes. The package comes with many types of documentation, including technical help pages with short code examples, longer code demos, and in-depth vignettes combining code, text and graphics, giving users a wide array of starting points for their own research. This paper provides a concise overview of the package and illustrates the new features using examples selected from the literature. Although the package does not provide a complete chemical speciation model, numerous examples from the package demonstrate the ease of reproducing selected published calculations and sometimes identifying issues with existing datasets and models.

A generalization of the results of the study of the composition of metal-bearing fluids of cobalt deposits of hydrothermal Genesis, formed in different geodynamic settings in connection with the formation of alkaline and alkaline-basite intrusions and dikes. To determine the physical and chemical parameters of ore deposition from fluid inclusions in minerals, both traditional and new instrumental methods of thermobarogeochemistry were used: thermo-and cryometry, RAMAN spectroscopy, concentration of ore and petrogenic elements in individual fluid inclusions were evaluated by LA-ICP-MS. The obtained results served as the basis for the study, the main task of which was the thermodynamic modeling of the conditions of joint transport and deposition of Co, Ni, Cu, Fe, Mg, Ca, Ag, Au, Bi, U, Pt and Pd C calculation of a number of equilibrium States of the hydrothermal system, the composition close to the natural ore-forming fluids. Physical and chemical factors of native deposits-gold, silver, platinum and palladium in the ores of such deposits are revealed. The obtained data can serve as a basis for the development of correct genetic models of ore-forming systems of cobalt deposits and contribute to solving the problems of their search.
