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 …

Tracking the final fate of subducting carbon is crucial to understanding global carbon cycles
and climate changes in the history of the Earth. Available geochemical tracers such as …

Geological evidence indicates that grounded ice sheets reached sea level at all latitudes
during two long-lived Cryogenian (58 and≥ 5 My) glaciations. Combined uranium-lead and …

The global biosphere is commonly assumed to have been less productive before the rise of
complex eukaryotic ecosystems than it is today. However, direct evidence for this assertion …

Isotope ratios of heavy elements vary on the 1/10000 level in high temperature materials,
providing a fingerprint of the processes behind their origin. Ensuring that the measured …

The zinc (Zn) stable isotope system has great potential for tracing planetary formation and
differentiation processes due to its chalcophile, lithophile and moderately volatile character …

Life requires a wide variety of bioessential trace elements to act as structural components
and reactive centers in metalloenzymes. These requirements differ between organisms and …

Zinc (Zn) is a key micronutrient for marine phytoplankton, with a global distribution that is
similar to silicic acid. The processes that govern this relationship, despite the very different …

Abstract Zinc (Zn) and cadmium (Cd) are important biologically active trace-metals in the
ocean. To date, the marine distributions of these elements have been understood primarily …

Zinc is an essential micronutrient and its concentration and isotopic composition in marine
sediments represent promising tracers of the ocean carbon cycle. However, gaps remain in …
