Fluorine partitioning between nominally anhydrous minerals (olivine, clinopyroxene, and plagioclase) and silicate melt using secondary ion mass spectrometry and newly synthesized basaltic fluorine microanalytical glass standards

Fluorine (F) is a volatile constituent of magmas and hydrous mantle minerals. Compared to other volatile species, F is highly soluble in silicate melts, allowing F to remain in the melt during magma differentiation and rendering F less subject to disturbance during degassing upon magma ascent.
