Halogens in the Earth’s Mantle: What We Know and What We Don’t

Klemme S, Stalder R

Zusammenfassung

The Earth’s mantle is known to contain significant amounts of volatile elements, such as hydrogen (H),carbon (C) and halogens. In the past decades our knowledge about the storage of H and C in mantleminerals, and their behavior during melting of mantle peridotite has improved considerably. In contrast,the behavior of other volatile elements, such as the halogens (Cl, F, I or Br) in the mantle is not so wellconstrained. Here we review the available experimental, analytical and theoretical data on halogen storagein mantle rocks and minerals, halogen concentrations in nominally halogen free minerals, and halogenpartitioning during magmatic processes
