资源简介：

Antimony (Sb) is a critical metal commodity and an indicator for the formation of some of the largest hydrothermal gold (Au) deposits. However, the conditions of extraction of Sb from granitic magmas and its transport by magmatic volatiles remains poorly understood. Here we will determine the partition coefficients of Sb between granitic melts and Cl/S-bearing aqueous fluids and its speciation to provide new insight into the formation of Sb(Au) deposits. Fluid-melt partitioning and speciation experiments will be performed in the FAME autoclave in conjunction with synchrotron X-ray Fluorescence (SXRF) and absorption (HERFD-XAS) spectroscopy analysis at BM16.
