Chalcogen isotopes reveal limited volatile contribution from late veneer to Earth
The origin of Earth's volatile elements is highly debated. Comparing the chalcogen isotope
ratios in the bulk silicate Earth (BSE) to those of its possible building blocks, chondritic …

A review of the development of Cr, Se, U, Sb, and Te isotopes as indicators of redox reactions, contaminant fate, and contaminant transport in aqueous systems
Summary Cr, Se, U, Sb, and Te are toxic, redox‐active elements that are more mobile and
environmentally problematic in their oxidized forms, and less mobile and bioavailable in …

Selenium isotopes as tracers of a late volatile contribution to Earth from the outer Solar System
The origin of Earth's volatiles has been attributed to a late addition of meteoritic material after
core–mantle differentiation. The nature and consequences of this 'late veneer'are debated …

Recycled selenium in hot spot–influenced lavas records ocean-atmosphere oxygenation
Oxygenation of Earth's oceans and atmosphere through time has consequences for
subducted surface signatures that are now stored in the mantle. Here, we report significant …

Comparative determination of mass fractions of elements with variable chalcophile affinities in geological reference materials with and without HF‐desilicification
Desilicification elevates extraction of Re and platinum‐group elements (PGEs) from many
geological reference materials (RMs), but the extent to which it affects less chalcophile …
