Zinc stable isotope fractionation during its adsorption on oxides and hydroxides.
TLDR
The results strongly suggest that inorganic processes controlling zinc isotope adsorption on soil and sediment minerals should be of second-order importance compared to biological factors.About:

Metal Stable Isotope Signatures as Tracers in Environmental Geochemistry
TL;DR: This review presents the application of metal stable isotopes as source and process tracers in environmental studies, in particular by using mixing and Rayleigh model approaches and the extent of natural isotopic variations for different elements is compared.

Metal Stable Isotopes in Paleoceanography
Ariel D. Anbar,Olivier Rouxel +1 more
TL;DR: In this paper, the basis of stable isotope fractionation as it applies to transition metals and metalloids is reviewed, analytical considerations, and the current status and future prospects of this rapidly developing research area.
Journal ArticleDOI
The Isotope Geochemistry of Zinc and Copper
TL;DR: Chaboy et al. as mentioned in this paper showed that the symmetry of the hexaaqua complex of Cu(H2O)62+ has a Jahn-Teller distortion effect (Sherman 2001; Bersuker 2006), whereby the two Cu-O distances of the vertical axial bond (Cu-Oax) are longer than four Cu O distances in the equatorial plane (Cu Oax).

Fractionation of Cu and Zn isotopes during adsorption onto amorphous Fe(III) oxyhydroxide: Experimental mixing of acid rock drainage and ambient river water
TL;DR: Fractionation of Cu and Zn isotopes during adsorption of the metal onto amorphous ferric oxyhydroxide was examined in experimental mixtures of metal-rich acid rock drainage and relatively pure river water and during batch adaption experiments using synthetic ferrihydrite.
Journal ArticleDOI
The oceanic mass balance of copper and zinc isotopes, investigated by analysis of their inputs, and outputs to ferromanganese oxide sediments
TL;DR: In this paper, the authors investigated the biogeochemical cycling of copper (Cu) and zinc (Zn) isotopes in the ocean and presented estimates for the isotopic composition of the inputs to the oceans based on new data presented here and published data.
