Rayleigh distillation model predicting the range of δ124/117Sn in the fluid that would evolve, assuming progressive precipitation from an evolving solution. F is the proportion of Sn in the magma relative to that in the fluid. The starting δ124/117Sn values of the GSP-2 is 0.61‰ relative to the Sn NIST SRM 3161a standard solution (Creech et al. 2017; She et al. 2020). The curves for a range of different α-fractionation factors for cassiterite [α = 0.983, from Creech et al. (2019); α = 0.99897, from She et al. (2020)] and pairs cassiterite-stannite [calculated based on the data from Yao et al. (2018)] are shown. (Color online.)
