Since their discovery in 1913, stable isotopes have become formidable tracers of physicochemical processes at all scales. Steady advances in mass spectrometry have allowed isotopic inquiries to move from the so-called “traditional” systems (i.e., H, C, N, O, and S) to heavier “nontraditional” systems (e.g., Fe, Mo, Ti, Zr, U) whose diverse geochemical characteristics are providing novel and complementary insights. Moving from micron-size systems (single crystals) to planetary-size bodies, the articles in this issue will explore the enormous range of temporal and physical scales over which heavy stable isotopes have provided paradigm-shifting insights into the evolution of our planet and solar system. We will also highlight new frontiers where novel stable isotope systematics appear particularly promising for unraveling long-standing questions.

v18n1 Heavy Stable Isotopes: From Crystals To Planets
GUEST EDITORS: Patricia L. Clay (University of Manchester, UK) and Hirochika Sumino (University of Tokyo, Japan)
The halogen group elements (F, Cl, Br, and I) are common in the terrestrial inventory, though often present in trace amounts in many Earth and planetary materials. The halogens play a key role in a variety of geologic environments and processes, from mineralization to their influence on the composition of Earth’s atmosphere when released as oceanic, volcanogenic, and anthropogenic emissions. Halogens act as “fingerprints” of fluid mediated processes on Earth and other planetary bodies. These “bioessential” elements are also critically important to human health. In this issue of Elements, we explore the role that the halogens play in shaping diverse planetary systems, from the surface of planets to their interiors. We also review the techniques that are suitable for the analysis of halogen elements and of isotopes of Cl and Br in terrestrial and extraterrestrial materials.
