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 …

Abstract The Middle Eocene Climatic Optimum (around 40 million years ago) was a roughly
400,000-year-long global warming phase associated with an increase in atmospheric CO2 …

Geochemists have long considered Li isotope composition of marine carbonates as one of
the most straightforward oceanic archives, tracing climate regulation by continental silicate …

In the Precambrian, reverse weathering—a process consuming oceanic silica, metal cations
and alkalinity to form marine clays—was a key control of the long-term carbon cycle …

Records of the lithium isotopic composition of seawater (δ 7 Li sw), preserved in the lithium
isotopic composition of shallow-marine carbonate sediments (δ 7 Li carb), provide …

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 …

To examine the alteration of river-derived sediments through a large estuary and the
implications for elemental cycling and global climate, this study analyses lithium (Li) …

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 …

The lithium isotope composition (δ7Li) of seawater records important information on the
evolution of the carbon and silicon cycles over geologic time. Here we report δ7Li values in …
