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 …

The weathering of silicate rock is a major sink of atmospheric CO 2 in the global carbon
cycle and thus controls global climate change. Lithium (Li) isotopes are considered to be a …

Abstract The terminal Ediacaran (∼ 551–541 Ma) was a critical period in Earth's history
witnessing the coupled evolution of tectonism, climate, marine environment, and …

The termination of the Cryogenian period marks a transition from an extreme ice-to a
greenhouse climate, likely initiated by increased atmospheric CO 2, however uncertainties …

Our current understanding of controls on δ 7 Li variability and fractionation mechanisms is
limited, complicating the interpretation of chemical weathering. The role of clay adsorption in …

Chemical weathering is one of the most important processes on the Earth's surface, and
lithium isotopes have been used as a promising tracer of silicate weathering, as the …

The stable isotopes of lithium (Li) serve as a robust proxy of silicate weathering. The fate and
transport of these isotopes in the dissolved load of major rivers have been characterized to …

We present comprehensive Li-C-Sr isotopic studies on two classic marine carbonate
sections (Yangdi and Dongcun) transecting the Late Devonian Frasnian-Famennian …

Contributions of geothermal reservoir and aquifer rock weathering to dissolved arsenic (As)
concentrations remain poorly understood. This study investigated geochemical and isotopic …

Reversible adsorption and isotope fractionation of boron on the surface of clay minerals is a
key process that impacts boron isotope cycling in porewater, rivers and the ocean. However …
