Magnesium isotope geochemistry
Magnesium (Mg) has an atomic number of 12 and belongs to the alkaline earth element
(Group II) of the Periodic Table. The pure Mg is a silvery white metal and has a melting point …

Metal stable isotope signatures as tracers in environmental geochemistry
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 …

Density functional theory estimation of isotope fractionation of Fe, Ni, Cu, and Zn among species relevant to geochemical and biological environments
This paper reports the values of reduced partition function ratios (as 1000 ln β) for Fe, Ni, Cu,
and Zn bound to a number of inorganic and organic ligands. We used Density Functional …
