Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

To improve our understanding and guide future studies and applications, we review the
biogeochemistry of the rare earth elements (REE). The REEs, which form a chemically …

Recent studies reveal that bioapatite and Fesingle bond Mn micro-nodules are
predominantly hosts of rare earth elements and yttrium (REYs) in bulk deep-sea sediments …

Many manganese (Mn) carbonate deposits over geologic history are often closely
associated with black shales. However, the mechanism (s) by which the Mn entered the …

Abstract The Rare Earth Elements (REE) archived in carbonate rocks retain a wealth of
information on paleo-seawater chemistry and local-regional redox conditions. However …

To investigate the use of cerium (Ce) in the upper continental crust (UCC) for tracing
oxidative weathering, we measured the Ce anomaly (Ce/Ce*), the Ce stable isotope …

The concentration of Eu relative to neighbouring rare earth elements (REE) is an important
tool in petrology and geobiology. In most sample matrices, precise and accurate middle REE …

Clay minerals are major carriers of rare earth elements (REEs) in ion-adsorption-type REE
deposits. Recent studies have revealed that REEs are hosted predominantly in …

Iodate ions can substitute for carbonate in crystal lattices, which is why carbonate-
associated iodine (CAI) is increasingly being used to track redox-sensitive iodine species …

Marine oxygenation during the Archean and Paleoproterozoic is poorly constrained. Iodine
in carbonate is a possible oxygen indicator. We obtained molar ratios of iodine to calcium …
