Early Cambrian black shales on the Yangtze Platform host a regionally distributed highly
metalliferous sulfide-rich carbonaceous unit which has been the subject of extensive debate …

Zinc and Ni are essential micronutrients whose stable isotope systematics in marine
sediments represent promising, but still develo**, tracers of past ocean chemistry and …

Heavy metal pollution is a serious environmental problem in the marine ecosystem.
Thereinto, marine transportation activities have gradually become an important source of …

To examine the alteration of river-derived sediments through a large estuary and the
implications for elemental cycling and global climate, this study analyses lithium (Li) …

In fewer than fifteen years, the study of Ni stable isotopes has advanced from early method
development to application of a powerful tool for resolving a long-standing question: why …

In marine sediments, formation of pyrite (FeS 2) is promoted by both organoclastic sulfate
reduction (OSR) and sulfate-driven anaerobic oxidation of methane (SD-AOM), and these …

Oil pollution can release trace metals (TMs) with cumulative toxicity into seawater, harming
marine ecosystems in the long term. However, the lack of studies has inhibited our …

Although the crucial role that dissolved trace metals (dTMs) play in both carbon cycling and
climate have been revealed over the past three decades, much about the oceanic budgets …

Nickel (Ni) is a bio-essential element for phytoplankton in the modern oceans, and yet, the
global ocean mass balance of Ni has puzzled scientists for decades. Many estimates of total …

In this study, we have investigated the evolution of concentrations and isotope ratios of
dissolved nickel (Ni), copper (Cu), and zinc (Zn) from the North Equatorial Current in the …
