Geochemical Perspectives is a journal independent of major publishing houses, entirely run and edited by and for the geochemical community. Geochemical Perspectives is published by the European Association of Geochemistry.


Each issue of Geochemical Perspectives presents a single article with an in-depth view on the past, present and future of a field of geochemistry, seen through the eyes of a highly respected member of our community. The articles combine science and history of the field’s development and the scientist’s opinions about future directions. We expect personal glimpses into the author’s scientific life, how ideas were generated, pitfalls and triumphs along the way, and how ideas were adopted to carry our field further. Perspectives articles are intended for the entire geochemical community, not for experts. They are not reviews or monographs or text books. They go beyond the current state of the art, providing opinions about future directions and impact in the field.

Siderophile Elements in Tracing Planetary Formation and Evolution
by Richard J. Walker

Abstract | Full text PDF (25MB)

The latest issue of Geochemical Perspectives examines the history of how siderophile elements have been applied to the study of planetary accretion, and what they can tell us about the mixing history of the mantle. The concentrations of moderately and highly siderophile elements in Earth’s mantle appear to tell two distinct tales. The moderately siderophile elements are present in abundances that are generally consistent with core-mantle segregation occurring at elevated pressures and temperatures, consistent with processes that may have occurred as Earth grew, at the base of one or more global magma oceans. By contrast, highly siderophile elements are present in the mantle in broadly chondritic relative abundances. This suggests they were added by process referred to as a late veneer or late accretion. Recent tungsten isotope data indicate that mantle domains created within the first few tens of millions of years after Solar System formation survived convective mixing for billions of years.
