Abstract

Using a micro-focused synchrotron X-ray beam, in situ X-ray fluorescence (XRF) spectra were obtained from aqueous fluids and haplogranite or jadeite melts at 0.3 to 1.3 GPa and 730°C to 830°C under varied concentrations of (Na, K)Cl. Partition coefficients between the aqueous fluids and melts were calculated for Pb, Rb, and Sr. There was a positive correlation between D values and pressure, as well as D values and salinity. The present data indicates the capacity of highly saline fluids to effectively transfer Pb and Rb. See Kawamoto et al., 2014, Earth, Planets and Space, www.earth-planets-space.com/content/66/1/61/
