A lack of knowledge about antimony (Sb) isotope fractionation mechanisms in key
geochemical processes has limited its environmental applications as a tracer. Naturally …

Schwertmannite affects the mobility of antimony (Sb) in acid mine drainage, yet the Sb
sorption mechanism remains elusive. In this study, the molecular-level mechanism and the …

Molybdenum preserved in organic-rich shales is a key archive employed in studying Earth's
past oxygenation and Life's evolution. In these shales, positive correlations between Mo and …

Magnesium isotopic compositions of a set of clay-rich saprolites developed on the Neogene
tholeiitic basalt from Hainan Island in southern China have been measured in order to …

Abstract The Paleoproterozoic Era was a time of remarkable importance in the redox
evolution of Earth's atmosphere and oceans. Here, we present a multi-proxy study of Mo, U …

We report results of experiments conducted to quantify the sense and magnitude of
cadmium stable isotope fractionation during sorption to synthetic birnessite (Mn …

Ferromanganese crusts cover all outcrops on Takuyo-Daigo seamount traversed during
remotely operated underwater vehicle (ROV) dives, except in places covered by foraminifera …

Abstract The Neoproterozoic–Cambrian transition was a key time interval in the history of the
Earth, especially for variations in oceanic and atmospheric chemical composition. However …
