摘要
A set of 201 experimental data on solubility of sulfur in silicate melts was collectedfrom literature to formulate the changes of sulfur solubility as a function of bulk compo-sition of the melts and pressure, temperature, and the fugacity of oxygen and sulfur. Aregular solution model and a polynomial function have been put forward, from which sol-ubility of sulfur in natural silicate magmas can be estimated. Synthetic application of twomethods makes it possible to evaluate activity of FeS in a silicate melt, which will be po-tentially valuable for predicting immiscibility of sulfide liquid in magmatic processes.
