Traditional stable isotope geochemistry involves isotopes of light elements such as H, C, N,
O, and S, which are measured predominantly by gas-source mass spectrometry (Valley et al …

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 …

Using microfluidic systems in liquid-liquid extraction process has distinctive advantageous,
including lower consumption and high extraction efficiency. In this research, the separation …

The intrinsic properties of the elements and their resulting behavior in natural systems
represent the underpinnings of geochemistry as a scientific discipline (Goldschmidt 1937) …

Groundwater-derived solute fluxes to the ocean have long been assumed static and
subordinate to riverine fluxes, if not neglected entirely, in marine isotope budgets. Here we …

We assessed the potential of Calcium (Ca) isotope fractionation measurements in blood (δ
44/42 Ca Blood) and urine (δ 44/42 Ca Urine) as a new biomarker for the diagnosis of …

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 …

Large predators are overabundant in mid-Cretaceous continental dinosaur assemblages of
North Africa. Such unbalanced ecosystem structure involves, among predatory dinosaurs …

Several studies have exploited the stable calcium (Ca) and strontium (Sr) isotope
compositions of marine carbonate rocks to investigate ancient carbon cycle dynamics …

The stable isotopes of calcium have tremendous potential for constraining the evolution of
the mantle as well as fingerprinting the recycling of carbon in the mantle via subduction. In …
