Zirconium and its stable isotopes in igneous systems
Zirconium, as a high field strength element, has been widely used to trace the differentiation
of terrestrial planets. It is also a major constituent in zircon, an important accessory mineral …

Combined Fe-Mg chemical and isotopic zoning in olivine constraining magma mixing-to-eruption timescales for the continental arc volcano Irazú (Costa Rica) and Cr …
Arc magmas commonly are mixtures of newly arriving primitive melts, stored magmas at
shallow levels, and xenolithic material added on ascent. Almost every eruption has a unique …
