Iron isotopic compositions are demonstrably powerful tracers of foundational planetary processes, including crust and core formation. In many volcanic environments, however, geochemical vestiges of these processes are obscured by the effects of magma

We present a compilation of Sr-isotopic data obtained on plagioclase from 27 samples covering the entire stratigraphy of the Northern Limb of the Bushveld Complex as determined by LA-MC-ICPMS. The lower parts of the Main Zone in the Northern Limb are

Silver isotope variations in chondrites: Volatile depletion and the initial 107Pd abundance of the solar system

Autor: Richard W. Carlson, Mary F. Horan, Maria Schönbächler, T. D. Mock, Erik H. Hauri

Publikováno v: Geochimica et Cosmochimica Acta. 72:5330-5341

The extinct radionuclide 107Pd decays to 107Ag (half-life of 6.5 Ma) and is an early solar system chronometer with outstanding potential to study volatile depletion in the early solar system. Here, a comprehensive Ag isotope study of carbonaceous and
