We have investigated trace-element partitioning between clinopyroxene and silicic melts ranging from 62 to 69 wt% SiO 2  in piston-cylinder experiments at 1.1 GPa and 1145.1155 °C. Run products consist of diopsidic clinopyroxene (with 3.5 wt% Al 2 O 3  and ~1 wt% Na 2 O) coexisting with silicic, aluminous, and alkaline melts. Clinopyroxene-melt partition coefficients for rare earth elements (REE) are significantly higher (e.g., D Sm  = 0.76 to 3.1) than previous studies of clinopyroxene-basaltic melt partitioning. The maximum D REE  is also shifted toward middle REE (e.g., Tb). Although the partition coefficients of Sr and Ti (D Sr  = 0.23.0.39, D Ti  = 0.28.1.0) are also elevated relative to clinopyroxenebasaltic melt, partition coefficients for Zr and Li (0.14.0.23 and 0.16.0.25, respectively) are within the range of literature values.

Effect of melt structure on trace-element partitioning between clinopyroxene and silicic, alkaline, aluminous melts
