Testing of sulfide solubility models and calculations of SCSS during crystallization of mafic magmas parental to layered intrusions

摘要

@@1 IntroductionOver the last 20 years, at least ten models for sulfide solubility in silicate melts have been proposed (Ariskin A.A et al., 2008; Boudreau, A.E., and Simon, A. ,2007) These models may be divided to three groups: ① those designed for systems open to sulfur fugacity . ② models based on the "sulfur capacity" concept (Fincham C. J. B. and Richardson F. D. , 1954), in which the effect of fS2 is accounted for implicitly, and ③ models describing system closed to sulfur, in which the sulfide saturation surface is considered to be a function of melt composition (including S2-), with temperature, pressure and fO2 being external intensive parameters (Holzheid, A. and Grove, T.L., 2002; Li, C, and Ripley, E.M. ,2005; Liu, Y et al., 2007; Mavrogenes, J. A. and O'Neill, H. St. C. ,1999).
