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


Abstract 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. Hence, the association between fluorine in basalts and fluorine in the mantle source region is more robust than for other volatile species. The ionic radius of F- is similar to that of OH- and O2-, and F may substitute for hydroxyl and oxygen in silicate minerals and melt. Fluorine is also incorporated at trace levels within nominally anhydrous minerals (NAMs) such as olivine, clinopyroxene, and plagioclase. Investigating the geochemical behavior of F... (more)
