Fluorine partitioning between eclogitic garnet, clinopyroxene, and melt at upper mantle conditions

Beyer, C; Klemme, S; Grützner, T; Ireland, Trevor; Magee, C. W; Frost, D. J


In this experimental study we obtained new mineral/melt (DF = cmineral/cmelt) partitioning data for fluorine in a bimineralic hydrous eclogite under Earth's upper mantle conditions (4–6 GPa, 1460–1550 °C). Omphacitic clinopyroxene displays mineral/melt partition coefficients between DF = 0.056 ± 0.005 and DF = 0.074 ± 0.001. Garnet partition coefficients are consistently lower with an average partition coefficient of DF = 0.016 ± 0.003. We found that omphacitic clinopyroxene is the dominant...[Show more]
