Compared with Phanerozoic strata, sulfate minerals are relatively rare in the Precambrian
record; this is probably due to the lower concentrations of sulfate in dominantly anoxic …

Marine barite is commonly used as a proxy to reconstruct past ocean productivity. Its
distribution in the water column mirrors organic carbon fluxes since it precipitates within …

The isotope composition of barium (Ba) in the mineral barite (BaSO 4) is emerging as a
powerful tracer of the pelagic Ba, carbon, and sulfur cycles. However, it is critical to identify …

In submarine environments, ferromanganese (Fe–Mn) oxides are formed via various
processes. Although hydrothermal Fe–Mn oxides are generally valueless as mineral …

In the modern marine environment, barium isotope (δ138Ba) variations are primarily driven
by barite cycling—barite incorporates' light'Ba isotopes from solution, rendering the residual …

Pelagic barite (BaSO 4) and related proxies are useful tools for reconstructing the marine
carbon cycle. The factors controlling pelagic barite dissolution in the ocean water column …

The marine biological pump is crucial for removing excess carbon dioxide from the
atmosphere to the ocean interior and seafloor sediments. The Late Miocene Biogenic Bloom …

Despite its critical role in regulating the global climate and carbon cycle, the evolution of
deep Pacific circulation has not been fully deciphered during the last glacial cycle. The effect …

Abstract The Cambrian Explosion coincided with a global greenhouse climate, but the
mechanism behind this warming event remains unclear, impeding our understanding of their …

The radiogenic isotope composition (eg 87 Sr/86 Sr and ε Nd) of the terrigenous fraction is
commonly used to determine the provenance and transport history of sediments. In ocean …
