Iodine speciation in basaltic melts at depth by Sanloup, Chrystèle, Leroy, Clémence, Cochain, Benjamin, Grützner, Tobias,  Chen, Qi, Kono, Yoshio, Shen, Guoyin

“…Iodine speciation in basalts therefore seems to reflect a trend amongst halogens, with lighter chlorine bonding to network modifying cations, and bromine changing affinity from network modifying cations to oxygen anions under pressure. In the absence of a fluid aqueous phase, iodine could thus reach the Earth’s surface in basaltic magmas as an oxide, not as a reduced species.…”
