Copper, a native metal found in ores, is the principal metal in bronze and brass. It is a
reddish metal with a density of 8920 kg m− 3. All of copper's compounds tend to be brightly …

The biogeochemical cycling of metals in natural systems is often accompanied by stable
isotope fractionation which can now be measured due to recent analytical advances. In …

Copper (Cu) is not only an essential metallic element for human and organisms, but also a
toxic and pernicious element when its environmental content exceeds a certain threshold …

Aims Recent advances in mass spectrometry have demonstrated that higher plants
discriminate stable Zn isotopes during uptake and translocation depending on …

We measured the Fe, Cu, and Zn isotopic compositions of the fluids generated during
leaching experiments with pyrite-, chalcopyrite-, and sphalerite-rich rocks and with a …

More than 70 microbiological studies of sulfidic mine dumps and heaps have been
published. The microbiology and the relevant biogeochemical processes in the dumps and …

Iron and copper isotopes are useful tools to track redox transformation and biogeochemical
cycling in natural environment. To study the relationships of stable Fe and Cu isotopic …

Recent reports suggest that significant fractionation of stable metal isotopes occurs during
biogeochemical cycling and that the uptake into higher plants is an important process. To …

The oxygenation of the atmosphere∼ 2.45–2.32 billion years ago (Ga) is one of the most
significant geological events to have affected Earth's redox history. Our understanding of the …

Copper isotopes may prove to be a useful tool for investigating bacteria–metal interactions
recorded in natural waters, soils, and rocks. However, experimental data which attempt to …
