The biogeochemical cycling of metals in natural systems is often accompanied by stable
isotope fractionation which can now be measured due to recent analytical advances. In …

Abstract Models test our understanding of processes and can reach beyond the spatial and
temporal scales of measurements. Multi-component Reactive Transport Models (RTMs) …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

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 …

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 …

Current understanding of the long-term carbon cycle posits that Earth's climate is stabilized
by a negative feedback involving CO 2 consumption by chemical weathering of silicate …

The long-term cooling, decline in the partial pressure of carbon dioxide, and the
establishment of permanent polar ice sheets during the Neogene period, have frequently …

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 …

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 silicon isotope composition of biogenic silica (δ 30 Si BSi) in the ocean is a function of
the δ 30 Si of the available dissolved Si (DSi; H 2 SiO 4), the degree of utilisation of the …
