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).
Journal ArticleDOI
Zinc isotope fractionation during magmatic differentiation and the isotopic composition of the bulk Earth
TL;DR: In this paper, the authors present high-precision Zn isotope analyses of two sets of chemically diverse, cogenetic samples from Kilauea Iki lava lake, Hawaii, and Hekla volcano, Iceland, which both show clear evidence of having undergone variable and significant degrees of magmatic differentiation.
Journal ArticleDOI
Stable Cu and Zn isotope ratios as tracers of sources and transport of Cu and Zn in contaminated soil
TL;DR: In this paper, the authors measured stable isotope ratios (δ 65 Cu, δ 66 Zn) in three soils at distances of 1.1, 3.8, and 5.3 kilometers from a Slovak Cu smelter and in smeltter wastes (slag, sludge, ash) to trace sources and transport of Cu and Zn in soils.
Journal ArticleDOI
Evaluation of zinc, cadmium and lead isotope fractionation during smelting and refining.
TL;DR: To evaluate metallurgical processing as a source of Zn and Cd isotopic fractionation and to potentially trace their distribution in the environment, high-precision MC-ICP-MS Zn, Cd and Pb isotope ratio measurements were made for samples from the integrated Zn-Pb smelting and refining complex in Trail, B.C., Canada.
Journal ArticleDOI
Sedimentary mercury stable isotope records of atmospheric and riverine pollution from two major European heavy metal refineries
TL;DR: In this article, the authors investigated sediment total mercury (Hg) concentrations and Hg stable isotopic compositions in the vicinity of two former non-ferrous metal (zinc) refineries in Lommel (Kempen, Belgium) and Viviez (Aveyron, France).

The geochemical evolution of the continental crust
TL;DR: A survey of the dimensions and composition of the present continental crust is given in this paper, where it is concluded that at least 60% of the crust was emplaced by the late Archean (ca. 2.7 eons).
Journal ArticleDOI
Precise analysis of copper and zinc isotopic compositions by plasma-source mass spectrometry
TL;DR: In this paper, a procedure for the analysis of Cu and Zn isotope compositions by plasma-source mass spectrometry (Plasma 54) together with a method to purify Cu and zn from natural samples of silicates, ores, sediments, and biological material is presented.
Journal ArticleDOI
Fifty-year sedimentary record of heavy metal pollution (Cd, Zn, Cu, Pb) in the Lot River reservoirs (France).
TL;DR: 137Cs activities and heavy metal concentration-depth profiles from sediment cores retrieved in 2001 from three reservoirs in the Lot River allow establishing a connection between the temporal evolution of the heavy metal pollution and historical changes in smelting and waste-treatment proceedings.

TL;DR: In this article, the results of a broadly based study on copper and iron isotope fractionation during various inorganic and biological processes were presented, showing that naturally occurring inorganic processes can fractionate Fe isotope to a detectable level even at temperature V1000C.
