The early to mid-Paleoproterozoic Lomagundi-Jatuli Excursion (LJE) is ostensibly the
largest magnitude (approximately+ 5 to+ 30‰), longest duration (ca. 130–250 million years) …

Abstract Otavi Group is a 1.5–3.5-km-thick epicontinental marine carbonate succession of
Neoproterozoic age, exposed in an 800-km-long Ediacaran− Cambrian fold belt that rims …

The rate of primary productivity is a keystone variable in driving biogeochemical cycles
today and has been throughout Earth's past. 1 For example, it plays a critical role in …

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 geochemistry of the carbonate sedimentary record is invaluable for understanding the
ancient seawater evolution of carbon and redox-sensitive elements. However, the …

Early marine and meteoric diagenesis is commonly proposed to alter the primary
geochemical signals of shallow-marine carbonates, hindering their use as a reliable archive …

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 …

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 …

Lithium isotope (δ 7 Li) variations in marine carbonate sediments and rocks have been
widely used to reconstruct global seawater Li isotope compositions and then trace the paleo …

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