Transient appearances of oxygen have been inferred before the Great Oxygenation Event (GOE)[∼ 2.3 billion years (Ga) ago] based on redox-sensitive elements such as Mo and S …
Indium is considered a critical element worldwide due to its specific function in low-carbon technology and its vulnerability to supply disruption. Although it occurs in a wide range of …

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 …
Economic interest in indium (In) and other critical metals has accelerated efforts to understand how such elements occur in nature and the controls on their mineralogy. In this …
Kīlauea Volcano's 2018 lower East Rift Zone (LERZ) eruption produced exceptionally high lava effusion rates and record-setting SO2 emissions. The eruption involved a diverse range …
Redox-driven copper (Cu) isotope fractionation has been widely observed in low- temperature weathering and hydrothermal processes. However, how Cu isotopes may …

In order to investigate possible Ca isotopic fractionation during basaltic magma differentiation, we measured Ca isotopic compositions of lavas recovered from Kilauea Iki …
The use of molybdenum as a quantitative paleo-atmosphere redox sensor is predicated on the assumption that Mo is hosted in sulfides in the upper continental crust (UCC). This …
