The lithium isotope system is increasingly being applied to a variety of Earth science studies,
as the burgeoning literature attests; over 180 papers have been published in the last twelve …

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 evolution of the global carbon and silicon cycles is thought to have contributed to the
long-term stability of Earth's climate,–. Many questions remain, however, regarding the …

The Paleocene-Eocene Thermal Maximum (PETM;~ 55.9 Ma) was a geologically rapid
warming period associated with carbon release, which caused a marked increase in the …

We report Li isotope composition (δ 7 Li) of river-borne dissolved and solid material in the
largest River system on Earth, the Amazon River basin, to characterize Li isotope …

The mid-Proterozoic, spanning 1.8 to 0.8 billion years ago, is recognized as a phase of
marine anoxia, low marine primary productivity (MPP), and constrained eukaryotic …

Seawater lithium isotopes (δ7Li) record changes over Earth history, including a∼ 9‰
increase during the Cenozoic interpreted as reflecting either a change in continental silicate …

Abstract Knowledge of the lithium (Li) isotope fractionation factor during clay mineral
formation is a key parameter for Earth system models. This study refines our understanding …

Lithium (Li) isotope analyses of sedimentary rocks from the Meishan section in South China
reveal extremely light seawater Li isotopic signatures at the Permian–Triassic boundary …

Biosilicification has driven variation in the global Si cycle over geologic time. The evolution
of different eukaryotic lineages that convert dissolved Si (DSi) into mineralized structures …
